Change the resolved.conf Cache option to a tri-state "no, no-negative, yes" values.
If a lookup returns SERVFAIL systemd-resolved will cache the result for 30s (See 201d995),
however, there are several use cases on which this condition is not acceptable (See systemd#5552 comments)
and the only workaround would be to disable cache entirely or flush it , which isn't optimal.
This change adds the 'no-negative' option when set it avoids putting in cache
negative answers but still works the same heuristics for positive answers.

Current operation of system-update-cleanup.service (removing /system-update
symlink and rebooting) implies that any update must complete *before*
system-update.target is reached.
Update recommendations to include explicitly setting
Before=system-update.target in services that use offline-updates mode.

Before only one comparison was allowed. Let's make this more flexible:
ConditionKernelVersion = ">=4.0" "<=4.5"
Fixes#12881.
This also fixes expressions like "ConditionKernelVersion=>" which would
evaluate as true.
Originally the description of conditions was brief, so it was acceptable
to put this part at the end. But now we have a myriad conditions, and
this crucial bit of information is easy to miss.
Takes a single /sys/fs/bpf/pinned_prog string as argument, but may be
specified multiple times. An empty assignment resets all previous filters.

Make possible to set NUMA allocation policy for manager. Manager's
policy is by default inherited to all forked off processes. However, it
is possible to override the policy on per-service basis. Currently we
support, these policies: default, prefer, bind, interleave, local.
See man 2 set_mempolicy for details on each policy.
Overall NUMA policy actually consists of two parts. Policy itself and
bitmask representing NUMA nodes where is policy effective. Node mask can
be specified using related option, NUMAMask. Default mask can be
overwritten on per-service level.
These options are pretty much equivalent to "journal" and
"journal+console" anyway, let's simplify things, and drop them from the
documentation hence.
For compat reasons let's keep them in the code.
(Note that they are not 100% identical to 'journal', but I doubt the
distinction in behaviour is really relevant to keep this in the docs.
And we should probably should drop 'syslog' entirely from our codebase
eventually, but it's problematic as long as we semi-support udev on
non-systemd systems still.)
