The disabling of features or components with the flag
--component-suggested/--feature-suggested didn't disable the suggested
ones but instead disabled all other ones. This is rather unintuitive due
to how the flags are named and also not really needed because the
intended reconciliation outcome can instead be done by first disabling
everything and then enabling the suggested ones again which is easier to
reason about. For components the tricky part is that they default to
enabled and thus it's better to have the disable/enable commands with
--component-suggested operate only on suggested ones instead of touching
others like "legacy" components that don't explicity say whether they
are enabled and suggested or not.
Make running disablement of components/features with
--component-suggested/--feature-suggested undo a previous enablement
with the same flags. Document how one can align the system to only use
suggested components/features and not anything else by doing it in two
steps, first disabling everything and then enabling suggested ones. This
also makes it clearer now that all components that are not explicitly
enabled nor suggested will be disabled then.
The auto-enable service should activate suggested components and
features but enabled all features which includes the default components
unsuggested features and any unsuggested features of the suggested
components. This is unexpected behavior and we rather want this service
to be limited to suggested features.
Switch the service flag to suggested and make the wording more explicit
in the man page. Also fix the wrong statement that it operates on
enabled components, it operates on all components, also explicitly
disabled ones.
This adds the scaffolding for being able to call sysupdate via varlink,
but it doesn’t yet define or implement any methods. Those will come in
following commits.
The existing `systemd-sysupdate.service` and `systemd-sysupdate.timer`
(which periodically ran `systemd-sysupdate update`) have been renamed
to `systemd-sysupdate-update.{service,timer}` to make way for a new
`systemd-sysupdate@.service` and `systemd-sysupdate.socket` file to
handle varlink activation.
Compatibility symlinks have been added for them.
This adds an operation equivalent to "systemd-sysupdate cleanup" after
an update completed (regardless if that update was entirely successful
or not). This ensures that any orphaned files are automatically cleaned
up, if they are not referenced by any transfer file's patterns anymore.
Follow-up for: d82e256bb9
Let's make sure we keep track of any file we drop into the system via a
database in /var/. This database is implemented based on symlinks, i.e.
reuses the fs as a simple database. Given the database most likely will
have <= 10 entries only (as we store *patterns* of installed file paths in
them, not the file paths themselves), this should be very efficient.
For implementation details see comments at top of
src/sysupdate/sysupdate-cleanup.c.
The `pending` and `reboot` verbs, as well as the `--reboot` switch, compare
the newest installed version against the booted OS version (IMAGE_VERSION= from
os-release). When a component is selected via --component=, this compares the
component's version against the unrelated host OS version, which by design live
in separate version spaces. The result is arbitrary reboot decisions: depending
on the relative version strings sysupdate would either always or never reboot.
Refuse the combination with a clear error instead of silently performing a
bogus comparison. Correctly tracking a per-component booted version is left as a
future feature.

These expose the two parts of ‘update’, so that update sets can be
acquired (downloaded) and installed (applied) in separate actions at
different times. For example, this could allow a load of update sets to
be acquired when online, and later applied when offline.

In mkosi, I want to add a sysupdate verb to wrap systemd-sysupdate.
The definitions will be picked up from mkosi.sysupdate/ and passed
to systemd-sysupdate. I want users to be able to write transfer
definitions that are independent of the output directory used by
mkosi. To make this possible, it should be possible to specify the
directory that transfer sources should be looked up in on the sysupdate
command line. Let's allow this via a new --transfer-source= option.
Additionally, transfer sources that want to take advantage of this
feature should specify PathRelativeTo=directory to indicate the configured
Path= is interpreted relative to the tranfer source directory specified
on the CLI.
This allows for the following transfer definition to be put in
mkosi.sysupdate:
"""
[Transfer]
ProtectVersion=%A
[Source]
Type=regular-file
Path=/
PathRelativeTo=directory
MatchPattern=ParticleOS_@v.usr-%a.@u.raw
[Target]
Type=partition
Path=auto
MatchPattern=ParticleOS_@v
MatchPartitionType=usr
PartitionFlags=0
ReadOnly=1
"""
This prevents sysupdate from going out to the network to enumerate
available instances. When combined with the list command, this lets us
query installed instances
This tries to add information about when each option was added. It goes
back to version 183.
The version info is included from a separate file to allow generating it,
which would allow more control on the formatting of the final output.
