Audit messages would be displayed as "unknown[1]".
Also specify AUTH as facility... This seems to be the closest match
(/* security/authorization messages */).
This file contains no privileged data — just names of devices to decrypt
and files containing keys. On a running system most of this can be inferred from
the device tree anyway.
Udev debug messages have to be significantly overhauled... For now
just downgrade those two. They are responsible for approximately 25%
of debug output during boot and are rather useless.
With debugging on, sysv-generator would print the full set of
lookup paths for *every* sysv script.
While at it, pass LookupPaths as a pointer in sysv-generator,
and constify it everywhere.

The second line already says everything.
it is ironic that
"The only purpose of this structure is to cast the structure pointer
passed in addr in order to avoid compiler warnings. See EXAMPLE below."

If you've got SELinux policy loaded, label_hnd is your labeling handle.
When systemd is shutting down, we free that handle via mac_selinux_finish().
But: switch_root() calls mkdir_p_label(), which tries to look up a label
using that freed handle, and so we get a bunch of garbage and eventually
SEGV in libselinux.
(This doesn't happen in the switch-root from initramfs to real root because
there's no SELinux policy loaded in initramfs, so label_hnd is NULL and we
never attempt any lookups.)
So: make sure that mac_selinux_finish() actually sets label_hnd to NULL, so
nobody tries to use it after it becomes invalid.

Coverity was complaining that CMSG_NXTHDR is used without
checking the return value. In this case it cannot fail, but
it is a good excuse to simplify the function a bit.
CID #1261726.
/dev/pts/ptmx is as important as /dev/pts, so error out if that
fails. Others seem less important, since the namespace is usable
without them, so ignore failures.
CID #123755, #123754.
