5704cd733c hostnamed: don't cache system UUID
There's no point in caching this. Let's always get this directly from
sysfs, so that we can never get out-of-date data here (after all this is
going to be cheap, and people might overmount it or so)

72f48cd3e3 hostnamed: don't cache uname() data
Let's not cache the uname(), it's very cheap to get it, and just means
we might get out of sync with what is current. After all, the data might
change IRL, due to setarch and stuff.

Usecase is also primarily debugging, but could be useful for other

f33cd69b5c condition: downgrade a few log messages to debug

841c0987f7 condition: check if path is absolute first
We should do this check first since it is done on the string itself
without any conditioning of system state otherwise. It is a weird to do
this test only if /etc is read-only.

6dbf352cfb meson: initialize time-epoch to reproducible builds compatible value
Debian Policy encourages to preserve timestamps whenever possible in the
tarballs, thus stable release updates of systemd usually do not bump NEWS file
timestamp. And thus time-epoch remains the same for the lifetime of a release.

It would be better, if each new stable release rebuild of systemd would bump
the time epoch a bit. But at the same time remain
reproducible. SOURCE_DATE_EPOCH is an environmnet variable defined for this
purpose. Thus if available, prefer that, instead of the NEWS file modification
time.

For example, on Debian/Ubuntu under the reproducible builds the
SOURCE_DATE_EPOCH is set to the timestamp from the packaging metadata, thus it
is incremented on every new stable release update, whilst preserving
reproducible builds capability.

f00c36641a pstore: introduce tmpfiles.d/systemd-pstore.conf
The systemd pstore service archives the contents of /sys/fs/pstore
upon boot so that there is room for a subsequent dump.  The issue is
that while the service is present, the kernel still needs to be
configured to write data into the pstore. The kernel has two
parameters, crash_kexec_post_notifiers and printk.always_kmsg_dump,
that control writes into pstore.

The crash_kexec_post_notifiers parameter enables the kernel to write
dmesg (including stack trace) into pstore upon a panic, and
printk.always_kmsg_dump parameter enables the kernel to write dmesg
upon a shutdown (shutdown, reboot, halt).

As it stands today, these parameters are not managed/manipulated by
the systemd pstore service, and are solely reliant upon the user [to
have the foresight] to set them on the kernel command line at boot, or
post boot via sysfs. Furthermore, the user would need to set these
parameters in a persistent fashion so that that they are enabled on
subsequent reboots.

This patch introduces the setting of these two kernel parameters via
the systemd tmpfiles technique.

b4e1563ffb Increase size of /run to 20%
For low memory machines (256MB), 10% of RAM for /run may not be enough for
re-exec of PID1 because 16MB of free space is required and /run may already
contain something.

cb1277fa3b udev: get rid of "Could not set flow control of" message on "lo" interface
When setting flow control attributes of an interface we first acquire
the current settings and then add in the new settings before applying
them again. This only works on interfaces that implement the ethtool
ioctls. on others we'll see an ugly "Could not set flow control of"
message, simply because we issue the SIOCETHTOOL ioctl once, for getting
the data. In particular we'll get it for the "lo" interface all the
time, which sucks hard. Let's get rid of it.
