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.
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.
sysexits.h has:
#define EX_CANTCREAT 73 /* can't create (user) output file */
EX_DATAERR is a copy-paste error from the previous sentence, which is
correct.
Similar as the other options added before, this is primarily useful to
provide comprehensive OCI runtime compatbility, but might be useful
otherwise, too.
This simply controls the PR_SET_NO_NEW_PRIVS flag for the container.
This too is primarily relevant to provide OCI runtime compaitiblity, but
might have other uses too, in particular as it nicely complements the
existing --capability= and --drop-capability= flags.
Previously, the container's hostname was exclusively initialized from
the machine name configured with --machine=, i.e. the internal name and
the external name used for and by the container was synchronized. This
adds a new option --hostname= that optionally allows the internal name
to deviate from the external name.
This new option is mainly useful to ultimately implement the OCI runtime
spec directly in nspawn, but it might be useful on its own for some
other usecases too.
This ensures we set the various resource limits of our container
explicitly on each invocation so that we inherit less from our callers
into the payload.
By default resource limits are now set to the same values Linux
generally passes to the host PID 1, thus minimizing needless differences
between host and container environments.
The limits are now also configurable using a new --rlimit= switch. This
is preparation for teaching nspawn native OCI runtime support as OCI
permits setting resource limits for container payloads, and it hence
probably makes sense if we do too.
What the man page said was different than what the code did.
save_external_coredump() will store the core temporarily for backtrace
generation, and will delete if afterwards if it is too large. So to disable
processing, it's necessary to both set
Storage=none/Storage=journal+JournalSizeMax=0/Storage=external+ExternalSizeMax=0
and ProcessSizeMax=0. This updates the man page to reflect the code.
The man pages are extended to describe that Storage=none + ProcessSizeMax=0 is
the simplest way to disable coredump processing. All the storage and processing
options make this quite complicated, so let's add a copy-and-pasteable example
of how to disable coredump. Doing it through coredump.conf has the advantage
that we still log, and the effect is immediate, unlike masking the sysconf
file.
Fixes#8788.
Commenting out "WatchdogTimeout=3min" in systemd-logind.service causes
NotifyAccess to go from "main" to "none", breaking support for logind
restart. Let's fix that.
Since StandardOutput=file:path is more similar to StandardInput= than
StandardInputText=, and only StandardInput= is actually documented above
StandardOutput= whereas StandardInputText= is documented below it, I
assume the intention was to refer to the former.
While set of systemd-journal-{gatewayd,remote,upload}.service services presents single subsystem on journald logs network transmission, systemd-journal-gatewayd.service description should also contain links to other parts of this subsystem: systemd-journal-remote.service and systemd-journal-upload.service.
* man: systemd-networkd-wait-online: systemd.service
While service type is mentioned (is a oneshot system service), link on systemd.service is added. 'See Also' section is also updated with link on systemd.service man-page.
Added short keys -u and -m for --unescape and --mangle respectively. These short keys are present in systemd-escape --help output and are absent in man systemd-escape page.
Add journal-upload.conf refentrytitle to have the same format to systemd-journal-remote.service description, which contains refentrytitle on journal-remote.conf in 'See Also' section.
