Allow to setup new bind mounts for a service at runtime (via either
DBUS or a new 'systemctl bind' verb) with a new helper that forks into
the unit's mount namespace.
Add a new integration test to cover this.
Useful for zero-downtime addition to services that are running inside
mount namespaces, especially when using RootImage/RootDirectory.
If a service runs with a read-only root, a tmpfs is added on /run
to ensure we can create the airlock directory for incoming mounts
under /run/host/incoming.
As described in #2680, systemctl did ignore inhibitors if it is not
attached to a tty to allow scripts to ignore inhibitors automatically.
This pull request preserves this behavior but allows scripts to
explicit check inhibitors if required.
The new parameter '--check-inhibitors=yes' enables this feature.
The old parameter '-i'/'--ignore-inhibitors' was deprecated in favor
of '--check-inhibitors=no', the default behaviour can be specified
with '--check-inhibitors=auto'.
The new parameter is also described in the documentations and shell
completions found here.
unset-environment is completed with variable names in the environment block.
set-environment the same, but suffixed with "=".
import-environment is completed with variable names in the client environment.
Timestamps for unit start/stop are recorded with microsecond granularity,
but status and show truncate to second granularity by default.
Add a --timestamp=pretty|us|utc option to allow including the microseconds
or to use the UTC TZ to all timestamps printed by systemctl.
Apparently both Fedora and suse default to btrfs now, it should hence be
good enough for us too.
This enables a bunch of really nice things for us, most importanly we
can resize home directories freely (i.e. both grow *and* shrink) while
online. It also allows us to add nice subvolume based home directory
snapshotting later on.
Also, whenever we mention the three supported types, alaways mention
them in alphabetical order, which is also our new order of preference.
Since cryptsetup 2.3.0 a new API to verify dm-verity volumes by a
pkcs7 signature, with the public key in the kernel keyring,
is available. Use it if libcryptsetup supports it.
Hiding the first column, which may contain bullet circles, with --no-legend
is undocumented and potentially unexpected. On the other hand, not printing
bullet circles with --plain is documented so hiding the column with that
switch is sensible.
The combination "--full --no-legend --no-pager --plain" is appropriate for
automated processing of systemctl output.
Add shortcuts to enable and start, or disable and stop, portable
services with a single portablectl command.
Allow to pass a filter on detach, as it's necessary to call
GetImageMetadata to get the unit names associated with an image.
Fixes#10232
v2:
- if RestartKillSignal= is not specified, fall back to KillSignal=. This is necessary
to preserve backwards compatibility (and keep KillSignal= generally useful).
