This makes two changes:
1. it resets the background color not only on NL (aka LF) but also on
CR, but without erasing things to the end of the line. This increases
compatbility with tools such as "less" which use CR to jump back to
the beginning of the line.
2. previously we'd not process series of newlines or ansi sequences
without intermediate other characters correctly, we'd always assume
what follows is regular text. Fix that, and correctly determine the
right state from the subsequent character.
Currently in many of our test cases you'll see a warning about a tun
device not being around. Let's make that quiet, since if there's no such
device there's no point in adding it to a policy anyway, and it makes
useless noise go away.
We keep the warning as a warning if a device node is missing for other
errors than ENOENT.
under some conditions we suppress generating BPF programs. Let's
systematically return 0 when we do this, and 1 if we did actually
soething, instead of second guessing this in the caller.
This is not only more correct, but allows us to suppress BPF programs in
more cases in later commits.
There's some unclarity whether major/minor of device nodes are supposed
to be "unsigned" or "dev_t". Various codebases assume the latter, but
glibc's major()/minor() types actually return a value typed to
"unsigned". On glibc dev_t is actually 64bit even if the kernel only
exposes 32bit. Hence this distinction kinda matters.
Let's clean things up a bit with handling: let's followe glibc's type
system here, and use unsigned (and not int).
Also let's pass invalid major/minor values around as UINT_MAX rather
than via pointers, to match how we usually do this, and to shorten our
code a bit. This is safe, since given the linux dev_t space being 32bit
only we can't possibly have a valid major or minor this hight, given
they must be smaller in size. While other archs disagree on the types of
major/minor, they also tend to have similar limits. In fact on FreeBSD
for example major()/minor() returns a signed int. Which would hence also
mean that UINT_MAX cannot be a valid major or minor.
Previously this function would log loudly in some cases but not in
others. Clean this up, and dont log at all, matching our coding style
which says we should either log in all error cases or in none.
Both callers of this function do logging already, hence no need to
duplicate it here.
Since 2e106312e2 the test unit fails with 'resources' result instead of
'exit-code', which the test didn't account for when running unprivileged.

The kernel-tools meta-package was retired in Rawhide, but its
replacement has not landed, yet. Until that happens, let's build without
the bpf-framework stuff.
Let's allow configuring the debug tty independently of enabling/disabling
the debug shell. This allows mkosi to configure the correct tty while
leaving enabling/disabling the debug tty to the user.
So the field contains simply the full name of the command being invoked,
hence rename the field to match the contents, and to mirror the
"short_identifier" field.
Interestingly, the field is apparently not actually used by anything
though! But we are not going to remove it, since a follow-up commit will
start making use of it.
Prompted by https://github.com/systemd/systemd/pull/30085#discussion_r1401534107.
Note, like Reconfigure bus method, even reconfiguration for an interface is
triggered by Reload method, the method only wait for the link enters
configuring state (or unmanaged state if no matching .network file exists).
Users still need to invoke systemd-networkd-wait-online if it is
necessary to wait for the interface enters configured state after Reload
medhod.
As described in https://github.com/systemd/systemd/issues/31235, the preset
state for systemd-homed-activate.service was unclear. On the one hand, we have
a preset with 'enable systemd-homed.service', and systemd-homed.service has
'Also=systemd-homed-activate.service systemd-homed-firstboot.service', so
'preset systemd-homed.service' would also enable those two services, but
'preset systemd-homed-activate.service' would disable it, because the presets
don't say it is enabled. It seems that this configuration is internally
inconsistent. As described in the issue, maybe systemctl should be smarter
here, or warn about such configs. Either way, let's make our config consistent.
Follow-up for d1f6e01e47 and
3ccadbce33.
This new mode copies resources provided by the client, so that they
remain available for inspect/detach even if the original images are
deleted, but symlinks the profile as that is owned by the OS, so that
updates are automatically applied.
The intro of systemd-firstboot is rewritten to make it clearer how it fits into
the big picture. Systemd does some machine-id and presets and
systemd-firstboot.service is used to interactively fill in the blanks.
Closes#22225.
