The UX of registering with the user session machined
instance is much better as there won't be an authorization
prompt. To make that available for users, let's add --user
and --system switches for vmspawn. For backwards compat, we'll
still try to register with the system machined instance if the
user machined instance is not available.
Currently, the Bash completions for journalctl tries to match the
previous word _**exactly**_, which leads to the following issue:
`journalctl -u dock` correctly auto completes to `journalctl -u
docker.service`, but `journalctl -eu` provides no completions at all,
which is a shame since I never use the `-u` option alone (almost always
`-eu` or `-efu`, I wish the `-e` option was the default but I digress).
The proposed solution is to assume words that start with only a single
dash and consist of only letters are short option groups and handle them
as if the previous word was the short option using the last character,
e.g. `-efu` -> `-u`.
The completion fails to complete to paths for verbs that need them when
a --param is the previous word, e.g.:
portablectl attach --runtime <tab>
fails to complete to paths
--empower gives full privileges to a non-root user. Currently this
includes all capabilities but we leave the option open to add more
privileges via this option in the future.
Why is this useful? When running privileged development or debugging
commands from your home directory (think bpftrace, strace and such),
you want any files written by these tools to be owned by your current
user, and not by the root user. run0 --empower will allow you to run
all privileged operations (assuming the tools check for capabilities
and not UIDs), while any files written by the tools will still be owned
by the current user.
The DBUS_SESSION_BUS_ADDRESS and DBUS_SYSTEM_BUS_ADDRESS parameters have
an interesting syntax thats useful to complete. Let's include a
completion definition for these parameters.
--no-hostname is one of the switches I use very often. In particular,
when looking at CI logs, the hostname is almost never interesting.
-H is not yet used in journalctl, because journal operates locally, but
will want it if display of remote journals is implemented. Use -W.
Both kernel-core and kernel-uki-virt call kernel-install upon removal. Need an additional argument to avoid complete removal for both traditional kernel and UKI.

The zsh completions only complete one type argument, even though multiple
args are allowed. But the same issue occurs with other completions, e.g.
for options. I don't know how to solve this.
Prefixes would be nice, but they appear to be very buggy.
A few examples:
- `udevadm test-builtin net_setup_link /sys<TAB><TAB>`: `/sysblock/`
- `udevadm test-builtin net_setup_link /sys/<TAB><TAB>`: `/sys/bin/`
- `journalctl /dev<TAB>`: `/dev//dev/`

We specify >= 0.62 as the supported version, so drop the duplicate name in all cases
where it is the same as outputs[0], i.e. almost all cases.
