It's pointless showing info that isn#t going to survive the current
invocation, hence hide it.
The "partition number" column is more useful since it kinda shows the
same information, but without the device node name prefixed that is
local to the currentl invocation.
These tests are already done at two places, let's unify them in one
place, and tweak them slightly (specifically: require for considering a
DDI bootable in UEFI we also need need an init system inside).
This reworks the image discovery logic, and conceptually allows DDIs
that are both confext and sysext to exist. Previously we'd only extract
one type of exension data from a DDI, with this we allow to extract both
if both exist.
This doesn't add support for true "multi-modal" DDIs, that qualify as
various things at once, it just lays some ground work that ensures we at
least can dissect such images.
This reworks 484d26dac1 quite a bit.
This changes systemd-dissect's JSON output, but given the
version with the fields it changes/dops has never been released (as the
above patch was merged post-v254) this shouldn't be an issue.
The ioctl() failure we handle gracefully, hence also reflect that in the
JSON output.
(While we are at it, bring JSON output into same order as textual
output, i.e. move uuid down a bit.)
This adds support for the new fsmount() logic of the kernel: we'll first
create an unattached fsmount fd, and then in a second step attach this
to some real file system inode – as opposed to attaching file system
directly. The benefit of this is that we can pass the open fsmount fds
over some sockets if need be, to isolate the mounting code from the
attaching code.
The subvolumes set is a set of source inodes similar to how the
denylist hashmap contains source inodes as keys. It indicates
directories in the source tree that should become subvolumes in
the target tree.
--copy-to, --copy-from, --list and --mtree are useful for image directories
as well as image files, so for those verbs, let's check if we were passed
a directory and skip all the image file setup if that's the case.
