Show hidden images in the completion results, but only if the current
word starts with ".", such that
- `machinectl clone <Tab>` will only offer non-hidden images, but
- `machinectl clone .<Tab>` will offer both hidden and non-hidden images
We already support -j as shortcut for JSON mode in various tools. Let's
add one more. We probably should add this systematically (at least where
it doesn't conflict with an existing -j switch with other purpose). But
I am too lazy to add that now.
The verb works only on running service units, so complete on that as the first
parameter, and a local file as the second. The other parameters are inside the
service namespace so we can't autocomplete from the outside, return early.
bootctl is rather useful to have, even if on a system without UEFI,
as it has a number of verbs that are unrelated to UEFI (e.g kernel-identify),
and more importantly, it supports --root to operate on directory trees
(which could be intended to be deployed on UEFI) so let's make sure we
always build it.
I'm not quite sure what the original intent of this line was, but it
doesn't work in the one call-site the "required" argument is actually
used. The "writable" flag was indexed as a scalar leaving only the
"e" to compare against.
Instead, let's just sort the parsed flags and compare the whole thing.
Also substitute "required" as a pattern, so that pattern based
comparisons may be supported.
