Currently the BLS snippets are named ostree-$ID-$VARIANT_ID-$index.conf,
but the BLS config files are actually sorted by using the version field
which is the inverse of the index.
In most places, _ostree_sysroot_read_boot_loader_configs() is used to
get the BLS files and this function already returns them sorted by the
version field. The only place where the index trailing number is used is
in the ostree-grub-generator script that lists the BLS files to populate
the grub config file.
But for some bootloaders the BLS filename is the criteria for sorting by
taking the filename as a string version. So on these bootloaders the BLS
entries will be listed in the reverse order.
To avoid that, change the BLS snippets filename to have the version field
instead of the index and also to have the version before deployment name.
Make the filenames to be of the form ostree-$version-$ID-$VARIANT_ID.conf
so the version is before the deployment name.

SPDX License List is a list of (common) open source
licenses that can be referred to by a “short identifier”.
It has several advantages compared to the common "license header texts"
usually found in source files.
Some of the advantages:
* It is precise; there is no ambiguity due to variations in license header
text
* It is language neutral
* It is easy to machine process
* It is concise
* It is simple and can be used without much cost in interpreted
environments like java Script, etc.
* An SPDX license identifier is immutable.
* It provides simple guidance for developers who want to make sure the
license for their code is respected

In almost all places. There are just a few exceptions; one tricky bit for
example is that the repo config must still have `mode=archive-z2`, since
`archive` used to mean something else. (We could very likely just get rid of
that check, but eh, later).
I also added a test that one can still do `ostree repo init --mode=archive-z2`.

This is a follow-up to https://github.com/ostreedev/ostree/pull/1097.
We make simple_write_deployment smart enough so that it can be used for
rpm-ostree's purposes. This is mostly an upstreaming of logic that
already existed there.
Notably we correctly append NOT_DEFAULT deployments *after* the booted
deployment and we now support RETAIN_PENDING and RETAIN_ROLLBACK flags
to have more granularity on deployment pruning.
Expose these new flags on the CLI using new options (as well as expose
the previously existing NOT_DEFAULT flag as --not-as-default).
I couldn't add tests for --retain-pending because the merge deployment
is always the topmost one. Though I did check that it worked in a VM.

Follow up to <https://github.com/ostreedev/ostree/pull/1079>; I was working on
the rpm-ostree updates for this, and I think it's more consistent if we have
`.img` here, since that's a closer match to the "remove $kver" that results in
`vmlinuz`. Also just best practice to have file suffix types where they make
sense.
The astute reader might notice this sneaks in a change where we'd crash if the
legacy bootdir didn't have an initramfs...yeah, should probably have test
coverage of that.

This is the new Fedora kernel standard layout; it has the advantage
of being in `/usr` like `/usr/lib/ostree-boot`, but it's not OSTree
specific.
Further, I think in practice forcing tree builders to compute the checksum is an
annoying stumbling block; since we already switched to e.g. computing checksums
always when doing pulls, the cost of doing another checksum for the
kernel/initramfs is tiny. The "bootcsum" becomes more of an internal
implementation detail.
Now, there is a transition; my current thought for this is that rpm-ostree will
change to default to injecting into both `/usr/lib/ostree-boot` and
`/usr/lib/modules`, and stop doing `/boot`, then maybe next year say we drop the
`/usr/lib/ostree-boot` by default.
A twist here is that the default Fedora kernel RPM layout (and what's in
rpm-ostree today) includes a kernel but *not* an initramfs in
`/usr/lib/modules`. If we looked only there, we'd just find the kernel. So we
need to look in both, and then special case this - pick the legacy layout if we
have `/usr/lib/modules` but not an initramfs.
While here, rework the code to have an `OstreeKernelLayout` struct which makes
dealing with all of the variables nicer.

I'd like to move the new canonical kernel directory to `/usr/lib/modules/$kver`,
as Fedora has done. The `get_kernel_from_tree()` function now abstracts over
parsing the data (src vs destination filenames, as well as checksum) in
preparation for adding the new case.
In preparation for this, let's change the current test suite to use the
*current* directory of `/usr/lib/ostree-boot`, and also add coverage of `/boot`.

See: http://marc.info/?l=linux-fsdevel&m=149520244919284&w=2
XFS doesn't flush the journal on `syncfs()`. GRUB doesn't know how to follow the
XFS journal, so if the filesystem is in a dirty state (possible with xfs
`/boot`, extremely likely with `/`, if the journaled data includes content for
`/boot`, the system may be unbootable if a system crash occurs.
Fix this by doing a `FIFREEZE`+`FITHAW` cycle. Now, most people
probably would have replaced the `syncfs()` invocation with those two
ioctls. But this would have become (I believe) the *only* place in
libostree where we weren't safe against interruption. The failure
mode would be ugly; nothing else would be able to write to the filesystem
until manual intervention.
The real fix here I think is to land an atomic `FIFREEZETHAW` ioctl
in the kernel. I might try a patch.
In the meantime though, let's jump through some hoops and set up
a "watchdog" child process that acts as a fallback unfreezer.

(Note this PR was reverted in <https://github.com/ostreedev/ostree/pull/902>;
this version should be better)
Using `${sysroot}` to mean the physical storage root: We don't want to write to
`${sysroot}/etc/ostree/remotes.d`, since nothing will read it, and really
`${sysroot}` should just have `/ostree` (ideally). Today the Anaconda rpmostree
code ends up writing there. Fix this by adding a notion of "physical" sysroot.
We determine whether the path is physical by checking for `/sysroot`, which
exists in deployment roots (and there shouldn't be a `${sysroot}/sysroot`).
In order to unit test this, I added a `--sysroot` argument to `remote add`.
However, doing this better would require reworking the command line parsing for
the `remote` argument to support specifying `--repo` or `--sysroot`, and I
didn't quite want to do that yet in this patch.
This second iteration of this patch fixes the bug we hit the first time;
embarassingly enough I broke `ostree remote list` finding system remotes.
The fix is to have `ostree_repo_open()` figure out whether it's the same
as `/ostree/repo` for now.
Down the line...we might consider having the `ostree remote` command line itself
instatiate an `OstreeSysroot` by default, but this maximizes compatibility; we
just have to pay a small cost that `ostree` usage outside of that case like
`ostree static-delta` in a releng Jenkins job or whatever will do this `stat()`
too.

This reverts commit 1eff3e8343. There
are a few issues with it. It's not a critical thing for now, so
let's ugly up the git history and revisit when we have time to
debug it and add more tests.
Besides the below issue, I noticed that the simple `ostree remote add`
now writes to `/ostree/repo/config` because we *aren't* using the
`--sysroot` argument.

https://bugzilla.gnome.org/show_bug.cgi?id=755787
With this patch, an admin (system builder) can now:
1) Edit /usr/lib/ostree-boot/uEnv.txt
2) Deploy the new tree. OSTree will append system's uEnv.txt
to the OSTree's managed uEnv.txt (loader/uEnv.txt).
It is common for u-boot systems to read in an extra env
from external /uEnv.txt. The same file OSTree uses to pass
in its env. With this patch /uEnv.txt now contains OSTree's
env + custom env added by system builders.

OSTree's code for testing predates the `glib-tap.mk` making its
way into GLib. Let's switch to it, as it provides a number
of advantages.
By far the biggest advantage is that `make check` can start to run
most of the tests *in addition* to having them work installed.
This commit keeps the installed tests working, but `make check` turns
out to be really broken because...our TAP usage has bitrotted to say
the least. Fix that all up.
Do some hacks so that the tests work uninstalled as well - in
particular, `glib-tap.mk` and the bits encoded into
`g_test_build_filename()` assume *recursive* Automake (blah). Work
around that by creating a symlink when installed to loop back.
I noticed in the static deltas tests, there were some tests that
should have been under `-o pipefail` to ensure we properly propagate
errors.
There were a few places where we were referencing undefined variables.
Overall, this is clearly a good idea IMO.
Eliminates the need for constantly passing --sysroot=sysroot, but
also makes ostree place remote configs for sysroot/ostree/repo in
sysroot/etc/ostree/remotes.d where they should have been all along.
The test-admin-deploy-1 was copied into -uboot at some point. But
really they should be testing exactly the same thing, except for
the bootloader backend.
Unify these tests by extracting a common test core.
