journal: don't remove the flushed flag when journald is stopped

Due to the fact that systemd-journal-flush.service has
"Requires=systemd-journald.service", this service is stopped too when journald
is requested to do so.

However stopping systemd-journal-flush.service implies that journald
relinquishes /var hence implicitly switching back to the volatile storage
mode and removing /run/systemd/journal/flushed.

If journald is started afterwards, it will run in volatile storage mode
regardless of the value of 'Storage=' as it believes now that /var is not yet
ready (because the flushed flag is missing).

Because this flag is mainly an indication for journald that the initialization
of /var/log/journal (during the boot process) has been done,
systemd-journal-flush.service shouldn't be tied to the state of journald itself
but to the state of /var/log/journal, hence to the state of the system.

Apparently the previous limit set on the max number of inodes for /dev was too

still pretty arbitrary (that said, not sure if it really makes sense to put

That's both confusing and redundant, as the nobody user still has primary group

So explicitly specify the primary group of the nobody user, and add a line
ensuring that that group exists.

This is not a problem for Debian (or Ubuntu) itself, as they add their own
version of basic.conf in their systemd build logic. But it appears on for

units: delay binfmt processing until after local-fs.target

Users may use rules that refer to binaries e.g. in /opt or /usr/local,
and those directories may be separate mount points. We don't need the

Note that this can *not* distinguish the case when

When `SELinuxContext=` parameter is prefixed with `-`, the documentation states
that any errors determining or changing context should be ignored, but this
doesn't actually happen and the service may fail with `229/SELINUX_CONTEXT`.

Fix by adding checks to `context->selinux_context_ignore`.

core: normalize 'r' variable handling in unit_attach_pids_to_cgroup() a bit

The 'r' variable is our "go-to" variable for error return codes, all
across our codebase. In unit_attach_pids_to_cgroup() it was so far used
in a strange way for most of the function: instead of directly storing
the error codes of functions we call we'd store it in a local variable
'q' instead, and propagate it to 'r' only  in some cases finally we'd
return the ultimate result of 'r'.

Let's normalize this a bit: let's always store error return values in
'r', and then use 'ret' as the variable to sometimes propagate errors
to, and then return that.

This also allows us to get rid of one local variable.

No actual codeflow changes, just some renaming of variables that allows
us to remove one.

4 years agochange indicator used for later versions of VirtualBox (#21127)

change indicator used for later versions of VirtualBox (#21127)

Detection of VirtualBox is accomplished in the existing code by *either* `innotek GmbH`
or `Oracle Corporation` existing in any of:

- /sys/class/dmi/id/product_name
- /sys/class/dmi/id/sys_vendor
- /sys/class/dmi/id/board_vendor
- /sys/class/dmi/id/bios_vendor

With Oracle's physical servers, both `/sys/class/dmi/id/sys_vendor` and
`/sys/class/dmi/id/board_vendor` contain `Oracle Corporation`, so those
servers are detected as `oracle` (VirtualBox).

VirtualBox has the following values in the latest versions:

- /sys/class/dmi/id/product_name: `VirtualBox`
- /sys/class/dmi/id/sys_vendor: `innotek GmbH`
- /sys/class/dmi/id/board_vendor: `Oracle Corporation`
- /sys/class/dmi/id/bios_vendor: `innotek GmbH`

Presumably the existing check for `innotek GmbH` is meant to detect
older versions of VirtualBox, while changing the second checked value
from `Oracle Corporation` to `VirtualBox` will reliably detect later and future
versions.

json: do something remotely reasonable when we see NaN/infinity

JSON doesn't have NaN/infinity/-infinity concepts in the spec.
Implementations vary what they do with it. JSON5 + Python simply
generate special words "NAN" and "Inifinity" from it. Others generate
"null" for it.

At this point we never actually want to output this, so let's be
conservative and generate RFC compliant JSON, i.e. convert to null.

One day should JSON5 actually become a thing we can revisit this, but in
that case we should implement things via a flag, and only optinally
process nan/infinity/-infinity.

This patch is extremely simple: whenever accepting a
nan/infinity/-infinity from outside it converts it to NULL. I.e. we
convert on input, not output.
