Introducing ostree-grub-generator ostree-grub-generator can be used to customize the generated grub.cfg file. Compile time decision ostree-grub-generator vs grub2-mkconfig can be overwritten with the OSTREE_GRUB2_EXEC envvar - useful for auto tests and OS installers. Why this alternative approach: 1) The current approach is less flexible than using a custom 'ostree-grub-generator' script. Each system can adjust this script for its needs, instead of using the hardcoded values from ostree-bootloader-grub2.c. 2) Too much overhead on embedded to generate grub.cfg via /etc/grub.d/ configuration files. It is still possible to do so, even with this patch applied. No need to install grub2 package on a target device. 3) The grub2-mkconfig code path has other issues: https://bugzilla.gnome.org/show_bug.cgi?id=761180 Task: https://bugzilla.gnome.org/show_bug.cgi?id=762220 Closes: #228 Approved by: cgwalters

boot: Add ostree-finalize-staged.path Rather than manually starting the `ostree-finalize-staged.service` unit, we can leverage systemd's path units for this. It fits quite nicely too, given that we already have a path we drop iif we have a staged deployment. To give some time for the preset to make it to systems, we don't yet drop the explicit call to `systemctl start`. Though we do make it conditional based on a DEBUG env var so that we can actually test it in CI for now. Once we're sure this has propagated, we can drop the `systemctl start` path and the env var together. Closes: #1740 Approved by: cgwalters

src/boot/ostree-remount.service \
Add an `ostree-boot-complete.service` to propagate staging failures 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.

src/boot/ostree-finalize-staged.path \
finalize-staged: Ensure /boot automount doesn't expire If `/boot` is an automount, then the unit will be stopped as soon as the automount expires. That's would defeat the purpose of using systemd to delay finalizing the deployment until shutdown. This is not uncommon as `systemd-gpt-auto-generator` will create an automount unit for `/boot` when it's the EFI System Partition and there's no fstab entry. To ensure that systemd doesn't stop the service early when the `/boot` automount expires, introduce a new unit that holds `/boot` open until it's sent `SIGTERM`. This uses a new `--hold` option for `finalize-staged` that loads but doesn't lock the sysroot. A separate unit is used since we want the process to remain active throughout the finalization run in `ExecStop`. That wouldn't work if it was specified in `ExecStart` in the same unit since it would be killed before the `ExecStop` action was run. Fixes: #2543
