We exported sd_id128_get_machine_app_specific() and
sd_id128_get_boot_app_specific(). But those operate on the current machine,
and sometimes the user might want to do the same calculation for a different
machine, or an earlier boot, etc. We expose the underlying implementation
to make this easy.
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.
The pipe stuff introduced in 701e0c2660 causes nspawn to switch the
console from 'interactive' into 'read-only' which is a bit useless when
debugging. Let's set --console=interactive explicitly in such case.
Follow-up to 701e0c2660.
This reverts commit 837773add465bd0a0d1f598203d297cf0129468b.
The original issue #27287 is fixed by #28123. Let's
reintroduce the test for systemd-update-utmp.
session_leave_vt may be called after the VT device was hung up, which
will cause vt_release to fail with -EIO. This is known to cause an issue
with GNOME 44 on Fedora where gdm-session-worker sometimes freezes when
trying to switch to VT 1 after a `loginctl terminate-user` operation.
Fix this by reopening the VT in session_leave_vt if we get an -EIO.
This partially reverts 3c1eee5beda642707037b189481c3c30d1668da7.
I thought that it is not necessary, but
https://mesonbuild.com/Reference-manual_functions.html#vcs_tag says:

We can use version_h directly, since we already have it.
Hopefully fixes https://github.com/systemd/systemd/issues/28994.
There's really no point in first extracting a command line from an UKI
to just pass it unmodified to the UKI. In particular as this is
systematically ignored in SecureBoot is enabled.
Let's drop this, so that unless the user actually edits the cmdline we
pass nothing to the invoked kernel.
Note that this low-key is a compat break, since the passed cmdline gets
measured. However, in the interest of minimized the difference between
systems with and without sd-boot to behave the same i think we should
suppress the command line anyway.
Chronyd and similar time services, when using PTP devices, may need
the BindsTo/After directives to ensure the devices are available
before starting. Tag PTP devices with systemd to allow for wider
adoption.

Previously, DHCP_STATE_STOPPED and DHCP_STATE_INIT are both handled as
not-running. Moreover, previously after sd_dhcp_client_start() is
called, the client still in INIT state (and thus handled as not-running)
even if its internal timer event sources are initialized.
Let's make only STOPPED state handled as not-running, and make the
client initially in STOPPED state.
Prompted by #28896.
Let's also use vcs_tag() when we're doing a non-git build. In those scenarios,
the build would normally be done just once in a given copy, so doing an extra
call does not matter. We can save a few lines of meson config.
The special path was added in 064b8e2c99ceb348c515353cc5c7d7bd05c49fcb, with
the justifaction that vcs_tag() is slow and -Dversion-tag=foo can be used to
fix the version tag and speed up partial rebuilds. I think the justification
for this is weak: having an accurate version tag is particularly useful when
developing the code. Shaving of a fraction of a second at the cost of having to
manually update the version seems iffy.
Secondly, with vcs_tag() we can be pretty sure that meson will build the
version file first and that it'll be available to all build steps. Because we
didn't use version tag, we had to manually specify the dependency on version.h
in various places. It seems nicer to use vcs_tag() and not have to deal with
this problem at all.
Finally, the savings in time seem much smaller than back when
064b8e2c99ceb348c515353cc5c7d7bd05c49fcb was made. It reported a change
from 94 ms to 521 ms. But now the difference seems to be about 50 ms:

ninja -C build 0.08s user 0.02s system 97% cpu 0.108 total
Overall, I think the tiny time savings are not worth the complexity.
The use of vcs_tag was dropped in #28567, which results in builds having
stale version information once new commit are made.
This also fixes a case where CI builds would have no version information
because they are checked out without any tags for git-describe to use.
Additionally, use `--git-dir` now, as that particular issues seems to
have been fixed by now.
We might inherit a max rlim value that's larger than the kernel's
maximum (nr_open). This will cause setrlimit() to fail as the given
maximum is larger than the kernel's maximum. To get around this,
let's limit the max rlim we pass to rlimit() to the value of nr_open.
Should fix#28965
