This new call allows explicit control of the "floating" state of a bus
slot object. This is useful for creating a bus slot object first,
retaining a reference to it, using it for making changes to the slot
object (for example, set a description) and then handing it over to
sd-bus for lifecycle management.
It's also useful to fix#8551.
In journal_file_set_online() the offline thread doesn't need to be
joined if it's been canceled before actually reaching the phase of
writing the offline state.
We usually seperate case statements within a switch from each other by
empty lines. We also often add an empty line after multi-line function
prototypes, let's do so here too
Also, no trailing ; after }...
This corresponds nicely with the specifiers we already pass for
/var/lib, /var/cache, /run and so on.
This is particular useful to update the test-path service files to
operate without guessable files, thus allowing multiple parallel
test-path invocations to pass without issues (the idea is to set $TMPDIR
early on in the test to some private directory, and then only use the
new %T or %V specifier to refer to it).
Usually, we order our settings in our unit files in a logical order,
grouping related settings together, and putting more relevant stuff
first, instead of following a strictly alphabetical order.
For specifiers I think it makes sense to follow an alphabetical order
however, since they literally are just characters, and hence I think the
concept of alphabetical ordering is much more commanding for them. Also,
since specifiers are usually not used in combination, but mostly used
indepdently of each other I think it's not that important to group
similar ones together.
No other changes except the reordering.
This makes it easier to link the nspawn implementation to the tests.
Right now this just means that nspawn-patch-uid.c is not compiled
twice, which is nice, but results in test-patch-uid being slightly bigger,
which is not nice. But in general, we should use convenience libs to
compile everything just once, as far as possible. Otherwise, once we
start compiling a few files here twice, and a few file there thrice, we
soon end up in a state where we are doing hundreds of extra compilations.
So let's do the "right" thing, even if is might not be more efficient.
When dealing with a large number of template instances, for example
when launching daemons per VRF, it is hard for operators to correlate
log lines to arguments.
Add a new with-unit mode which, if available, prefixes unit and user
unit names when displaying its log messages instead of the syslog
identifier. It will also use the full timestamp with timezones, like
the short-full mode.
