This is a one-time tree wide reformatting to ensure consistency
going forward.

update all existing deployments in place
Example:
$ sudo ostree admin kargs edit-in-place --append-if-missing=rw
See https://github.com/ostreedev/ostree/issues/2617
This will not add duplicate key, if there is `TESTARG=VAL1` in the
kernel arguments, `--append-if-missing=TESTARG=VAL2` will be ignored.

Quite a while ago we added staged deployments, which solved
a bunch of issues around the `/etc` merge. However...a persistent
problem since then is that any failures in that process that
happened in the *previous* boot are not very visible.
We ship custom code in `rpm-ostree status` to query the previous
journal. But that has a few problems - one is that on systems
that have been up a while, that failure message may even get
rotated out. And second, some systems may not even have a persistent
journal at all.
A general thing we do in e.g. Fedora CoreOS testing is to check
for systemd unit failures. We do that both in our automated tests,
and we even ship code that displays them on ssh logins. And beyond
that obviously a lot of other projects do the same; it's easy via
`systemctl --failed`.
So to make failures more visible, change our `ostree-finalize-staged.service`
to have an internal wrapper around the process that "catches" any
errors, and copies the error message into a file in `/boot/ostree`.
Then, a new `ostree-boot-complete.service` looks for this file on
startup and re-emits the error message, and fails.
It also deletes the file. The rationale is to avoid *continually*
warning. For example we need to handle the case when an upgrade
process creates a new staged deployment. Now, we could change the
ostree core code to delete the warning file when that happens instead,
but this is trying to be a conservative change.
This should make failures here much more visible as is.

Add API to write a deployment state to `/run/ostree/staged-deployment`,
along with a systemd service which runs at shutdown time.
This is a big change to the ostree model for hosts,
but it closes a longstanding set of bugs; many, many people have
hit the "losing changes in /etc" problem. It also avoids
the other problem of racing with programs that modify `/etc`
such as LVM backups:
https://bugzilla.redhat.com/show_bug.cgi?id=1365297
We need this in particular to go to a full-on model for
automatically updated host systems where (like a dual-partition model)
everything is fully prepared and the reboot can be taken
asynchronously.

Example user story: Jane rebases her OS to a new major version N, and wants to
keep around N-1 even after a few upgrades for a while so she can easily roll
back. I plan to add `rpm-ostree rebase --pin` to opt-in to this for example.
Builds on the new `libostree-transient` group to store pinning state there.

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
See http://spdx.org for further reading.

This is a similar approach as
https://github.com/projectatomic/rpm-ostree/commit/12c34bb2491a07079c911ef26401fee939e5573c.
One thing to note is when we parse the admin related functions,
we still keep the old admin related flags, and added a new parameter
to represent the command struct.
This allows us to identify the caller of the function, making it
easier for us to possibly deduplicate the subcommand handling in
the future. A similar approach is done in rpm-ostree:
https://github.com/projectatomic/rpm-ostree/commit/83aeb018c1012c7a43783c09b74ec71bc9c45826
This also makes it easier for us to change the prototype of the function.
If we want to add something new in the future, we won't need to touch every prototype.

We added a `.dir-locals.el` in commit: 9a77017d87b74c5e2895cdd64ad098018929403f
There's no need to have it per-file, with that people might think
to add other editors, which is the wrong direction.

I'm trying to improve the developer experience on OSTree-managed
systems, and I had an epiphany the other day - there's no reason we
have to be absolutely against mutating the current rootfs live. The
key should be making it easy to rollback/reset to a known good state.
I see this command as useful for two related but distinct workflows:
- `ostree admin unlock` will assume you're doing "development". The
semantics hare are that we mount an overlayfs on `/usr`, but the
overlay data is in `/var/tmp`, and is thus discarded on reboot.
- `ostree admin unlock --hotfix` first clones your current deployment,
then creates an overlayfs over `/usr` persistent
to this deployment. Persistent in that now the initramfs switchroot
tool knows how to mount it as well. In this model, if you want
to discard the hotfix, at the moment you roll back/reboot into
the clone.
Note originally, I tried using `rofiles-fuse` over `/usr` for this,
but then everything immediately explodes because the default (at least
CentOS 7) SELinux policy denies tons of things (including `sshd_t`
access to `fusefs_t`). Sigh.
So the switch to `overlayfs` came after experimentation. It still
seems to have some issues...specifically `unix_chkpwd` is broken,
possibly because it's setuid? Basically I can't ssh in anymore.
But I *can* `rpm -Uvh strace.rpm` which is handy.
NOTE: I haven't tested the hotfix path fully yet, specifically
the initramfs bits.

See projectatomic/rpm-ostree#42 for rationale. There are two high
level use cases:
- If the OS comes unconfigured, this is a way to point it at a repo of your choice.
- To switch between repositories while keeping the same branch easily.

Refactor command-line parsing to better utilize GOptionContext. This
eliminates most of the manual parsing and global options are now shown
in the help output.
Here's a sample:
$ ostree admin --help
Usage:
ostree admin [OPTION...] --print-current-dir|COMMAND
Builtin "admin" Commands:
cleanup
config-diff
deploy
init-fs
instutil
os-init
status
switch
undeploy
upgrade
Help Options:
-h, --help Show help options
Application Options:
--sysroot=PATH Create a new OSTree sysroot at PATH
-v, --verbose Print debug information during command processing
--version Print version information and exit

There are going to be a few utilities that are only useful for
installers and disk image creation tools. Let's not expose them all
at the toplevel; instead, hide them under "instutil".

Code like rpm-ostree generates disk images directly. In order to
ensure SELinux labeling is correct, it currently has a helper program
that runs over the deployment root, then over the whole disk and to
only set a label if none exist.
In order to make it easier to write installers such as Anaconda
without having them depend on rpm-ostree (or whatever other
build-server side program), pull in the helper code here.
|
|
|
|
|

This is something I want to make easier, as it better showcases the
flexibility of OSTree.

At the moment, just a container for a path, but we will start moving
admin functionality here.
|
|
|
|
|

Pass through GCancellable, and just use GFile *sysroot, since that's
all OtAdminBuiltinOpts was.
|
|
|
|
|
|
| |
Otherwise it's really easy to keep accumulating deployments. Also, we
may want to run this after rebooting, so we're back down to one
operating system.
|
|
|
|
|
|
|
| |
Calling it "cleanup" is better since it does more than repo pruning.
We were also doing a prune twice; ot_admin_cleanup() already does one,
so drop the bits to do it in cleanup.c.
|
|
|
|
| |
It's just less tedious, and we're GCC/LLVM specific anyways.

Originally, the idea was that clients would replicate "OS/tree"s from
a build server, but we'd run things like "ldconfig" on the client.
This was to allow adding e.g. the nVidia binary driver.
However, the triggers were the only thing in the system at the moment
that really had expected knowledge of the *contents* of the OS, like
the location of binaries.
For now, it's architecturally cleaner if we move the burden of
triggers to the tree builder (e.g. gnome-ostree or RPM). Eventually
we may want OSTree to assist with this type of thing (perhaps
something like RPM %ghost), but this is the right thing to do now.

See https://wiki.gnome.org/OSTree/DeploymentModel2
This is a major rework of the on-disk filesystem layout, and the boot
process. OSTree now explicitly supports upgrading kernels, and these
upgrades are also atomic.
The core concept of the new model is the "deployment list", which is
an ordered list of bootable operating system trees. The deployment
list is reflected in the bootloader configuration; which has a kernel
argument that tells the initramfs (dracut) which operating system root
to use.
Invidiual notable changes that come along with this:
1) Operating systems should now come with their etc in usr/etc; OSTree
will perform a 3-way merge at deployment time, and place etc in
the actual root. This avoids the need for a bind mount, and is
just a lot cleaner.
2) OSTree no longer bind mounts /root, /home, and /tmp. It is expected
that the the OS/ has these as symbolic links into /var.
At the moment, OSTree only supports managing syslinux; other
bootloader backends will follow.

This is intended for use by QA tools that want to manipulate a
loopback-mounted disk image or the like.

In some cases we want the ability to run triggers independently of
checking out a tree. For example, due to kernel limitations which
impact the gnome-ostree build system, we may need to run triggers on
first boot via systemd.
Secondarily, if the user installs a system extension which adds a new
shared library to /usr/lib for example, the system will need to run
the triggers again.
Also, I think I want to take triggers out of the core and put them in
ostree admin anyways.

The real vision of OSTree is to "multiple versions of multiple
operating systems". Up until now, it's worked to install gnome-ostree
inside a host distribution, but several things don't work quite right
if you try to do completely different systems.
In the new model, there's the concept of an "osname" which encompasses
a few properties:
1) Its own /var
2) A set of trees deployed in /ostree/deploy/OSNAME/
3) Its own "current" and "previous" links.
Now it no longer really makes sense to boot with "ostree=current".
Instead, you specify e.g. "ostree=gnome/current".
This is an incompatible change to the deployment code - you will need
to run init-os gnome and redeploy.
All "ostree admin" subcommands now take an OSNAME argument.
|
|
|
|
|
|
| |
Should be used when initializing a new root filesystem for a "pure
OSTree" system; for example, what "ostbuild privhelper-deploy-qemu"
does when creating a filesystem image loopback.
|
|
|
|
|
|
|
|
|
|
|
| |
After a while of pull-deploy cycles, you start to accumulate a lot of
them. While the deployment read-only part is hardlinked, the -etc
space adds up.
Additionally, the repository itself just gets large.
The new command "ostree admin prune" deletes everything except the
"current" and "previous" deployments.
|
|
|
|
| |
Fetch the latest for the current tree, and deploy it in one go.
|
|
This helps us avoid polluting the global binary namespace.
