This is a followup to https://github.com/projectatomic/rpm-ostree/pull/888
but more comprehensive; in the layering case, the sanitycheck runs
after all the `%posttrans` scripts, so we'll get a consistent error message
for the `rm -rf /` test.
We also do the sanitycheck for the "pure ostree" case, as well as cases
where we didn't actually layer packages (including `ex override remove` as
well as simply regenerating an initrd).
There's obviously a lot more we could do in a sanitycheck; as I say in the
comment it's tempting to consider trying to boot systemd (in a fully volatile
config), but for now let's do this. In the end of course the admin has rollback
too.

Now that we require clients to have an active session to RegisterClient,
we can't use runuser to check for non-root functionality. Add a new
vm_cmd_as() function to allow connecting as a different user. While
we're there, do some minor cleanups to consistently use `local` when
possible.

This test would actually fail even if the bin user were allowed to
install a package because there are no enabled repos to install. Fix it

I was thinking today about our script handling, and I realized
an excellent way to showcase the advancement rpm-ostree makes
over traditional package managers is the fact that we survive a
`%post` script that does `rm -rf /`!
See e.g. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=858521
It's been this way ever since we first implemented package layering;
the fact that we construct a new root and use bubblewrap to sandbox
makes us very resilient to this type of thing.
But, let's add a test case for this to be sure we preserve this behavior; for
example, if in the future we for some reason we decide to leak some host state
into the scripts.

This is required for glibc-all-langpacks at least:
https://bugzilla.redhat.com/show_bug.cgi?id=1367585
Otherwise, its usage is...extraordinarily rare. In fact looking at a snapshot of
`rpm-specs-20170518.tar.xz` from Fedora, the only other use is in
`postfix.spec`, and it appears bogus (the value is already expanded at build
time).
But the glibc case is special, as the value of `install_langs` is indeed
potentially dynamic per system.

The `install` command in CentOS 7 is too old to understand that
`-Dt foo/bar` means creating both `foo` and `bar`, which is useful so

Add experimental support for replacing packages from the base layer with
local RPMs. This is useful for example, to cherry pick a fixed package,
or to roll back to a previous package version. Like with pkg removals,
only files in /usr are actually replaced.
This patch also contains a few usability improvements as well, e.g.
showing the full NEVRA of removed packages rather than just their names,
and support for resetting overrides using either the pkgname or NEVRA.

Seen in the wild with `vagrant`'s use of `%post -p /usr/bin/ruby`. This was a
very easy fix, and actually makes the code a little bit nicer, as we no longer
need to explicitly make the script executable, since we now pass it as
`argv[1]`, the same way librpm does. That in turn would make it possible to fix
the TODO and use `bwrap --file`, but that can come later.

Nuke all the previous goop that was used to create RPMs at `make check`
time and transition all the tests to use the new `build_rpm` function.
It definitely feels cleaner to use. It's also really nice to have the
spec live in the same file as the test that uses it.
Closes: #854

The property of removal overrides dropping out if the package was
removed from the base layer felt a bit too magical and hacky. We really
should remember that wish and re-apply it if the pkg comes back. This is
similar to package layering: requests can become inactive (seems like a
better word than "dormant") if the package is already part of the base
layer, but they don't really go away.
This patch reworks the logic so that removal overrides work the same
way. In the status output, we now have both "RemovedBasePackages" and
"InactiveBaseRemovals" (which is only printed in verbose mode),
similarly to how we have "LayeredPackages" and "InactiveRequests". And
similarly, we also print out in the upgrader during a transaction all
the inactive base removals.
Another cool thing is that we now allow any pattern to be specified at
the CLI. E.g. `ex override remove /usr/bin/strace` will resolve to
strace.

This was a kind of last-minute bug introduced when I tweaked the
checkout to use `.` to avoid a `mkdir()` for files. But there were
multiple bugs with that; for files that are in subdirectories of `/etc`
we obviously need to get the right subdir and not use `/etc`.
Second, we need to handle the case where we're adding new subdirectories.
This change fixes `rpm-ostree install firewalld + rpm-ostree ex livefs`.

This is a valid case when layering local RPMs. Otherwise (e.g. if
specific non-local packages are requested), give the nicer error rather

There are a few different use cases here. First, for layering new packages,
there's no good reason for us to force a reboot. Second, we want some support
for cherry-picking security updates and allowing admins to restart services. Finally,
at some point we should offer support for entirely replacing the running tree
if that's what the user wants.
Until now we've been very conservative, but there's a spectrum here. In
particular, this patch changes things so we push a rollback before we start
doing anything live. I think in practice, many use cases would be totally fine
with doing most changes live, and falling back to the rollback if something went
wrong.
This initial code drop *only* supports live layering of new packages. However,
a lot of the base infrastructure is laid for future work.
For now, this will be classified as an experimental feature, hence `ex livefs`.

Now that rpm-ostree operations are cumulative, we need to make sure we
also clean up pending deployments. Also clean up the rollback for
consistency.
We also strengthen our ref handling. Always nuke the vmcheck ref (which

recreate it from the original ref.

Conceptually: we're going to move rpm-ostree and ostree at the same
cadence most of the time; for both releases *and* for git master.
The problem so far has been the latter part. Reusing FAHC
for the build gets us half of the problem.
The other trick I realized we can do - just pull ostree out from the build
container. This avoids fetching it from the internet, and makes my workflow for
hacking on both nicer - I just `sudo make install` in my build container for
ostree.
It's tempting to make the whole thing symmetric and require `sudo make install`
for rpm-ostree and not do the insttree thing but...perhaps after.

I originally thought there was a bug here, but missed we were skipping

symlinks.

1. Don't require an ssh-config
In the case of redhat-ci, the VMs are already fully configured for the
system (injected in the hosts file, host key accepted, etc...). So
there's no need to have an ssh-config there. In general, it should be
acceptable to run the vmcheck suite against a resolvable host without
having to create an ssh-config for it.
2. Make the host name configurable
Rather than hardcoding "vmcheck" as the hostname, allow overridding it
by specifying a VM env var directly. We also prepare the various scripts
to make use of the $VM variable whenever host-specific dirs/files are
created so that parallel runs won't step on each other.

While reading a recent conversation about GPG checking at treecompose
time, I had a sudden thought - were we actually doing verification
client side? Turned out, we aren't. That happens as part of
`dnf_transaction_commit()` which we don't use.
That function verifies every package at one go, but for us I think it's better
to do it before "importing". We shouldn't have untrusted bits that we've
unpacked (they might have suid binaries, for one thing).
This is an embarassing problem, but it's worth emphasizing that everyone should
be retrieving repodata at a minimum over TLS, which sets a baseline. On RHEL, we
already do pinned TLS, and there are discussions about extending that elsewhere.

We don't want to expose the host's `/tmp` since that means scripts could

Clean up the output of vmcheck a bit by printing out ssh debug details

See https://github.com/projectatomic/rpm-ostree/issues/233 - for RPMs which
place files in e.g. `/opt`, we have different behavior in the treecompose case

Since the unpacker right now is only used in the layering case, this just
ensures we'll get a consistent error there.

We sometimes talk about using `ostree admin undeploy`, but that
doesn't know about the pkgcache, and hence space there leaks
until the next rpm-ostree operation.
Just for this, we need to expose a cleanup command (and API). But
we also need to support cleaning:
- repomd
- downloads (repo/tmp)
So let's start implementing that.
Closes: #614
Approved by: jlebon
Until now, we always used the booted deployment, and would
garbage collect the "pending" deployment. This is the
way OSTree was designed, but I think for rpm-ostree given
how mutable we are on the client side, there's a much stronger
argument for being more stateful too.
This is a relatively simple code change to split the "merge deployment"
concept into two. There's now the "config merge deployment" and the
"origin merge deployment".
Basically, `rpm-ostree install foo; rpm-ostree install bar` will
now install both `foo` and `bar`. But we will still use the booted
deployment for `/etc`.
Down the line, I think I'd like to drive into OSTree the concept of
a "staged" deployment, that has the hardlink checkout done, but doesn't
have the config merge.
But we don't need to change the OSTree core for this yet; we can
do it here in rpm-ostree, and this relatively simple code change
fixes many issues at once.
For example, `rpm-ostree upgrade && rpm-ostree install foo` now
does what you expect as well.
Obviously, we want to enable doing multiple things in *one* transaction,
and we're not far away, but I think this is also the right thing to do now.
I'm relatively confident it won't break anyone's workflow, as what
we did before wasn't generally that useful. However, people will
need to learn to `ostree admin undeploy 0` if they *don't* want
this behavior. (We need to have `rpm-ostree cleanup`).

I'm watching https://github.com/rpm-software-management/libdnf/pull/199 and I
really don't like it. We already have a place to put out-of-rpmdb metadata,
which is in the ostree commit for imported packages. No need to involve a
relational database for this (and further, one that would need to learn about
multiple ostrees).
We're not yet *using* this information in the UI, but we could; imagine
changing the `status` `Packages:` to show packages-per-repo or so. We
could also expose an `rpm-ostree pkg-info foo`.
But for now, let's just start recording this.
Closes: #610

One thing that's very confusing about OSTree is there are two layers -
deployments and the refs/commits. If one does an `rpm-ostree upgrade`, but then
e.g. `ostree admin undeploy 0`, you still have the new revision in the repo.
We don't do a good job of displaying this state, or helping people clean
it up.
Down the line, I also want to better support something like `rpm-ostree pull` to
cache updates explicitly *without* deploying.
This commit just adds a bit of information to the status display. We might want
to have better formatting, but I think this an OK start.

The actual problem I am trying to fix with this is fallout from the
introduction of `/usr/libexec/rpm-ostreed`, which required a SELinux
policy change. Specifically for CentOS, the base policy is rev'd
slowly.
My hope was that by merging the daemon code back into `/usr/bin/rpm-ostree`
which is labeled `install_exec_t`, starting via systemd would do
the right thing. It turns out that doesn't happen.
Now later, I'm picking this patch back up because I want to do multprocessing in
the daemon (and in the core), and it makes sense to share code between them,
because multiprocessing will need to go through a re-exec path.
Another benefit is we avoid duplicated text (libglnx, internal helpers) between
the two binaries.

When we checked out the base tree for package layering, we would create
the directory in which ostree did the checkout. This meant however that
ostree wouldn't apply xattrs on the root directory itself. This would
cause the directory to be mislabeled (as system_conf_t instead of
root_t), which in turn cause SELinux violations on reboot when systemd
tried to make the root mount shared.
This patch fixes this by first settling on a permanent directory in
which to do checkouts -- really, we'll never have multiple package
layering operations going on at the same time. Once we know that we have
a reserved path, we can safely let ostree create it for us with the
proper xattrs.

Currently we push for a model where the initramfs is
generated (in non-hostonly mode), and merely replicated.
However, to support a few unfortunate corner cases like dm-multipath which wants
to inject a config file into the initramfs, we need to support regenerating it
client side too.
Down the line, we'll need this to support overriding the kernel too.
This changes things in the core to add the concept of an "empty"
`RpmOstreeContext`. I initially tried skipping it, but that was too much
duplication. We still want all of the core ostree-related logic that lives in
that code too.
The treespec bits barfed if the spec didn't have a `tree/packages` key. It was
simplest to change that to allow it - and because that was the only case where
we errored out in parsing, I dropped the error handling.
There was another place in the upgrader that now needed to be fixed to handle
transitioning from just regenerating initramfs to not.

I think since I landed a change to `--enable-new-name`, `/usr/bin/rpm-ostree`

In the container build + vagrant test workflow, we have to run `make

However, when using git worktrees (which is useful in this scenario to
avoid having to overwrite your local builds) and a CentOS build
container, the git inside is too old to understand worktrees, so let's
avoid invoking git in any of the test harness scripts.
Also make sure to restorecon after installing the new rpm-ostreed.

My development environment is now using "pet" docker containers.
I use VMs for testing things that require that (like rpm-ostree).
This patch builds on work from @jlebon in
https://github.com/projectatomic/rpm-ostree/pull/509
to rework `vmcheck` such that it can work on any `ssh-config`. By
default we expect this to be Vagrant.
However, I go a lot farther and delete the `vmbuild` code that was
trying to do builds in a container on the target VM. I think this is
still worth pursuing at some point, but for now I think it's
reasonable to assume that the rpm-ostree developer audience uses Linux
as their host workstation and hence has containers.
(There's another important point here in that for developing lower
level things like rpm-ostree, there's a strong push to make the VM
disposable and not a pet)
