systemd-255 is failing a build with the latest kernel headers… Let's downgrade
this warning, because it's fine if there's a file system we don't know about
and it makes thing less brittle if we don't treat this as a hard error.
(I initially conditionalized this on BUILD_MODE, but I don't think we need a
hard error there either. A warning will be noticed and fixed.)
The linux/ headers include linux/libc-compat.h that makes sure the
linux/ headers won't redeclare symbols already declared by net/if.h, but
glibc's net/if.h doesn't do that, so if the include order is reversed
we'll end up with a bunch of errors about redeclared stuff:

This also drops remaining workarounds from the last time this issue was
brought up (6f270e6bd8) since they shouldn't be needed anymore if the
order of the includes is the "correct" one. I also added a comment to
each affected include when this is inevitably encountered again in the
future.
Resolves: #32160
When adding unprivileged nspawn support we don't really want a global
lock file, since we cannot even access the dir they are stored in, hence
make the concept optional.
Some minor other modernizations.
This is similar to uid_range_load_userns() but instead of reading the
uid_map off a process it reads it off a userns fd.
(Of course the kernel has no API for this right now, hence we fork off a
throw-away process which joins the user namespace, and then read off the
data from there.)
gcrypt is used only for journal sealing operations in libsystemd, so it
can be made into a dlopen dependency that is used only on demand. This
allows to reduce the footprint of libsystemd in the most common cases.
Keep systemd-pull and systemd-resolved with normal linking, as they are
executables, and usually built with OpenSSL support anyway.
Currently app_1.0.raw is refused if it contains extension-release.d/extension-release.app,
which stops one from using versioned images without using the force flag to disable
the check. Relax it so that only the actual name, and not the version, is compared, like
it already happens in other places.
Identify an virtualbox instance even if product_name, sys_vendor and bios_vendor reflect the
information of the real hardware, by checking if board_vendor == "Oracle Corporation"
This fixes#13429 again
The previous fix was removed in #21127
For CI in mkosi, I want to configure systemd to log at debug level
to the journal, but not to the console. While we already have max
level settings for journald's forwarding settings, not every log line
goes to the journal, specifically during early boot and when units
are connected directly to the console (think systemd-firstboot), so
let's extend the log level options we already have to allow specifying
a comma separated list of values and lets allow prefixing values with
the log target they apply to to make this possible.
I didn't know that this helper existed… It is very similar to strdup_to_full(),
but all callers can actually be replaced by strdup_to(), which has more fitting
semantics.
