I'm working on supporting `override replace ./kernel-*.rpm`:
https://github.com/projectatomic/rpm-ostree/issues/946
But after battling the "installonly" logic in libdnf, I was confused why we
still had the files in `/usr/lib/modules`. It turned out to be because we only
remove files in `/usr`, but the code didn't handle UsrMove compat links.
There are a variety of approaches to fix this. Obviously a lot
of things get nicer in jigdo mode as we do UsrMove canonicalization
on import, and we could change this code to walk the imported pkg
ostree ref.
Another approach would be to walk the initial symlink, and check whether or not
it's the same as `/usr` (i.e. let the kernel do it).
For now though, what I chose to do was to scan the rootfs and find the UsrMove
compat links (i.e. we avoid hardcoding them again here). This is
fewer syscalls than the above and works well in practice.

This is what a lot of other tools do. It can get very verbose, with a
potentially huge amount of output if things are trickling in. This way
we're at least more friendly to someone running `cmd: rpm-ostree upgrade`
via Ansible or equivalent.
The slight hack here is that we *do* output `100%` on non-ttys to ensure we
print the result of the task.

This patch introduces a new `AutomaticUpdatePolicy` configuration. This
was a long time coming for rpm-ostree, given that its update model makes
it extremely apt for such a feature.
The config supports a `check` mode, which should be very useful to
Atomic Workstation users, as well as a `reboot` mode, which could be
used in its present form in simple single node Atomic Host situations.
There is still a lot of work to be done, including integrating
advisories, and supporting a `deploy` mode. This feature hopefully will
be leveraged as well by higher-level projects like GNOME Software and
Cockpit.

In #875 AKA b46fc35901 we
added support for the `releasever` option in treefiles. I am
pretty sure it worked at the time...but I didn't add tests.
Either it never worked or some refactoring broke it. The whole chain of
`GKeyFile` → `GVariant` is so confusing. Anyways fix it by copying the string.
Now let's use it by default in the compose tests, and while we're here bump
those to F27.
I'm doing this patch now as I was playing with doing a compose from
the `/usr/share/rpm-ostree/treefile.json` and wanted to use the stock
`.repo` files.

It obviously shouldn't block the ability to install, and anyways

one we can revisit supporting this.

When I tried to use my WIP client patches to do:
`rpm-ostree rebase rojig://fahc:fedora-atomic-host`,
I got a missing file object which turned out to
be the client importing the i686 RPMs.
This was passing in the test suite because we don't mirror i686 of course, but
on the client side right now we end up using all enabled repos, and since Fedora
is multiarch, the behavior is going to be...not predictable.
Thinking a bit about on this problem I actually happened to recall
the RPM `%{_isa}` macro which is used in Fedora in various places;
for example to "arch bind" `-devel` packages to their base. See
for example [this case](33c7dc02bc/f/ostree.spec (_79)) in libostree.
As I noted at first, the core problem here is that the "final"
RPM architecture field is not symmetric in any way with the definition
of that `%{_isa}` macro. See:
d9d47e0114/installplatform (L25)
The *third* solution I ended up on here is to iterate over the
`Provides` on the server side and we take the first thing
that matches `Provides: %{name}(whatever)`.
I briefly thought about trying to somehow drive into libsolv the
logic to prefer the jigdoRPM's native architecture...IIRC yum did
something like that in the past but it was never done in libsolv?
Anyways the dependencies here are now more correct, so other tools
will also handle it.

For CI purposes at least, these features are already part of FAH and the

This reverts commit 1ef259ed76.
Basically, for historical POSIX compatibility, `errexit` doesn't work at
all inside functions called from an if-statement/boolean context. This
is something I had already learned (and forgotten) when hacking on PAPR.
There are ways around this, but it's just not worth the added complex

I spent some time trying to figure out why on CentOS my changes to
`/etc/rpm-ostreed.conf` didn't seem to have any effect. It turns out
that for some reason I didn't spend too much time looking into, the
autoconf in CentOS defaults to `${prefix}/etc` when `--prefix` is given.
This is also why I was under the erroneous assumption that D-Bus config
files were in `/usr/etc` in CentOS. This patch fixes that as well.

Let's standardize on the default config file when running tests. We copy
the original out of the way and install the default one so tests can do
whatever they want with it.
This also strengthens the post-test cleanup to make sure we rebase back
to the local vmcheck branch, in case we're somehow on a different branch
with the exact same commit.

This fixes an asymmetry we introduced when rendering using the `ostree://`
prefix; we now support parsing it as well. We reject the `rojig://` prefix
explicitly for now.
On the implementation side...things are messy. My thought is that we do our best
to canonicalize at the entrypoints for both the client side as well as the
server side. However, for backwards compatibility we can't go all the way to
writing out `ostree://` to disk in the origin files.
I'm actually uncertain if Cockpit will deal with this...need to test that.

This is essentially a revert of #1190. I initially changed from storing
the epoch, version, and release separately to together to avoid endian
issues with epoch. This works around that instead by just encoding it as
a string.
As is done in our custom NEVRA printer (which before #1190 we used
here), we make sure that epochs of "0" are not printed as part of the
`nevra` or `evr` members.
Closes: #1198

Basically we're choosing the libdnf behavior of omitting `Epoch: 0` which IMO is
the sane thing to do even though in *theory* they're different RPMs but
who would ever ship both without incrementing release/etc?

`grep` supports checking multiple fixed strings separated by newlines,

Following up on `--ex-jigdo-output-rpm`, add support for writing the entire set
to an output directory. This is intended for use cases like FAHC, where we're
generating data outside of the upstream Fedora infrastructure. Further, we want
to support having our own history stored reliably, even if upstream prunes RPMs.
Now, this can be interesting even for upstreams like Fedora, as it naturally
captures just the subset of RPMs; doing full history support for that would
likely be a lot more palatable than for Everything.

Part of the goal of jigdo ♲📦 is to support organizations switching to *only*
providing RPMs. An intermediate step there is to "lock" the repo and jigdo
together; we don't want to update the ref if building the jigdoRPM fails.
Add an option to perform `rpm-ostree compose tree` and `rpm-ostree ex
commit2jigdo` together; notably we generate a commit, but only update the ref
once the jigdoRPM is built.

Basically the `rpmostree_context_relabel()` call we had in the treecompose path
for unified core didn't actually have any effect as the core code did a relabel
and unset the array.
I think this may actually be a regression from: https://github.com/projectatomic/rpm-ostree/pull/1137
though I didn't verify.
Anyways looking at this, the code is a lot simpler if we change the API so that
the "normal" relabeling is folded into `rpmostree_context_assemble()`. Then we
change the public relabel API to be "force relabel" which we use in the unified
core 🌐 treecompose path.
This shrinks the jigdoRPM for FAH from 90MB to 68MB.

This fixes a large swath of compatibility issues, for the same reasons as
overlayfs makes a lot of things Just Work. The ugly part of course is
doing hidden copyups inside the filesystem.
We've gone quite a long time with the "pure rofiles" mode, and have made changes
to various bits of userspace to be compatible with it. But what finally made me
give up on that is glibc's locale-archive; there's a patch for it that
is stalled, but even if it was applied we would still need to work with
older glibc.
This issue comes to the fore in unified core 🌐 mode, as without this
we won't get a correct locale archive.

This is the first step towards unifying how we introspect packages from
a specific commit. We currently do this in three ways: libdnf, librpm,
and now `rpmostree.rpmdb.pkglist`. I'd like to get to a point where we
only have `rpmostree.rpmdb.pkglist` and libdnf, the latter only when
more complex queries are required.
This patch teaches the `db diff` command to make use of the new db diff
API so that it can work even on metadata-only commits. This is relevant
for use cases mentioned in #558.
I didn't get rid of the `rpmhdrs_diff` functions right now because of
the `--changelogs` option: libdnf currently does not expose this, so we
fall back to the previous API in that case. OTOH, I wonder how much it's
actually used in the wild; maybe we could just nix it?

To make the new pkglist metadata even more usable, let's insert it
sorted. This ensures that we can bsearch the GVariant on the
client-side.
Enhance the bsearch utility function we have to deal with duplicate key
names. Although this is not the case today in rpm-ostree-managed streams
I know, some packages are allowed to have multiple versions installed,
so let's make sure we handle that deterministically by always returning
the first (earliest) version of the package.

The new `rpmdb.pkglist` metadata is a cheap way of retrieving the set of
packages in a commit. I'd like to make use of it as much as possible vs.
checking out the rpmdb and setting up a DnfSack.
Of course, in the case of layered commits, it doesn't matter *as* much,
because a layered commit being present in the repo should mean that a
deployment is currently using it, and we should learn to reuse the rpmdb
checkout of that deployment. Though keeping it consistent across both
server and client commits makes implementing `OstreeDeployment`-agnostic
things like `db diff` more efficient too. I also plan to use this in the
upcoming auto-update code.

This fixes another thing broken with `compose --ex-unified-core`;
for e.g. `/usr/bin/ping` from `iputils`, the classic example of a filecaps
binary.
As I'm writing this commit message I realize it will actually also
take effect for package layering unnecessarily; we'll pointlessly
break the hardlink. But eh, it doesn't matter right now, we can
optimize that later.

Rather than entirely symlinking `systemctl` → `/bin/true`, in order
to e.g. have NetworkManager be enabled, we need to process presets.
This is one of the things that's breaking FAHC where I did a
`--ex-unified-core` deployment.
(Actually it's a bit tempting to run a mass preset pass at the end,
but for now let's do this)
Implementation note: this is our first use of GResources, which
is a handy way to embed data into our final binary.

This rolls up several libglnx changes: https://github.com/GNOME/libglnx/pull/101
Now of course things are trickier here because we have an internal
abstraction over directly emitting to a console versus sending the
result over DBus. Further complicating things is that some things
call into libdnf and thus *require* use of `DnfState` which does
not give us the "n items" information, versus other parts which
we implement and can do what we want.
Even *further* complicating things is that we have to take care around non-CLI
callers like Cockpit; so I didn't try to pass the "n items" over DBus, rather
just reimplemented the "insert into text" that libglnx is doing.
Anyways overall this looks better IMO for all cases.

For a no-op `rpm-ostree upgrade` (i.e. no updates available), as long as
layering is enabled, we pay the cost of checking out the base tree, *mostly*
only to get the base rpmdb.
This is prep for fixing that down the line by knowing we always have the "base"
tree's rpmdb checked out. Then in the layering case we only modify
`/usr/share/rpm` (eventually that will point to `/usr/lib/sysimage/rpm`).
Teaching `rpmostree-core.c` about this can follow on later.

Having the "jigdo set" in repodata makes it so we can parallel download the
jigdo RPM with the set. However for now, I kept the jigdo set in the jigdoRPM,
since that way it'll be covered by the signature.
Also, this changes the way we inject metadata to use a magic comment string,
since trying to pass a gigantic macro to `rpmbuild` via its argv didn't work out
so well (it looks like rpmbuild eats newlines). This approach is more robust.

`user.ostreemeta`).
It looks like I had this working in some of the old unified core WIP patches,

We don't want to have to download all of `/usr/share/rpm` just to get

that's done, conceptually we just need to call
`ostree_repo_commit_modifier_set_sepolicy()`. However, I had
to drop the "number of files changed" since currently the libostree
API doesn't support that.
Also, in order to detect the case that content changes at all (so
we still have some useful information in the journal), implement
a "content hash" check.

Note this PR requires [bubblewrap 0.2.0](https://github.com/projectatomic/bubblewrap/releases/tag/v0.2.0).
Change our bwrap invocations drop truly dangerous capabilities like
`cap_sys_admin` and `cap_sys_module` just like Docker does today. Because of the
popularity of Docker, we can be pretty sure that most RPM scripts should have
adapted to this (although a problematic area here is that traditional librpm
doesn't actually error out if scripts fail).
There are two reasons to do this:
- We want "offline" updates by default; updates shouldn't affect the
running system. If we prepare the new root in the background, a
%post shouldn't restart a service for example. We already "handle"
this by making `systemctl` a symlink to `/bin/true`, but this approach
also shuts off `%post`s that do e.g. `insmod`.

Tracking issue: https://github.com/projectatomic/rpm-ostree/issues/1081
To briefly recap: Let's experiment with doing ostree-in-RPM, basically the
"compose" process injects additional data (SELinux labels for example) in an
"ostree image" RPM, like `fedora-atomic-host-27.8-1.x86_64.rpm`. That "ostree
image" RPM will contain the OSTree commit+metadata, and tell us what RPMs we
need need to download. For updates, like `yum update` we only download changed
RPMs, plus the new "oirpm". But SELinux labeling, depsolving, etc. are still
done server side, and we still have a reliable OSTree commit checksum.
This is a lot like [Jigdo](http://atterer.org/jigdo/)
Here we fully demonstrate the concept working end-to-end; we use the
"traditional" `compose tree` to commit a bunch of RPMs to an OSTree repo, which
has a checksum, version etc. Then the new `ex commit2jigdo` generates the
"oirpm". This is the "server side" operation. Next simulating the client side,
`jigdo2commit` takes the OIRPM and uses it and downloads the "jigdo set" RPMs,
fully regenerating *bit for bit* the final OSTree commit.
If you want to play with this, I'd take a look at the `test-jigdo.sh`; from
there you can find other useful bits like the example `fedora-atomic-host.spec`
file (though the canonical copy of this will likely land in the
[fedora-atomic](http://pagure.io/fedora-atomic) manifest git repo.
