We checked the wrong field, which was always NULL here, so we would always
reject the assignment. We would also print the wrong string in the error
message:
$ sudo systemd-run --socket-property ListenFIFO=/tmp/fifo3 cat
Failed to start transient socket unit: Invalid socket path: FIFO
When an ExtensionImages= extension-release metadata does not match, the
log messages (unless debug level is set) are pretty much incomprehensible:
systemd[463]: run-u11.service: Failed to set up mount namespacing: /run/systemd/unit-extensions/0: Stale file handle
systemd[463]: run-u11.service: Failed at step NAMESPACE spawning /usr/bin/echo: Stale file handle
Add an explicit log message if we get ESTALE from the dissect code, to
make it clear what's happening without needing to enable debugging:
systemd[463]: Failed to mount image /tmp/app3.raw, extension-release metadata does not match the lower layer's: ID=debian VERSION_ID=11 SYSEXT_LEVEL=11
Only treat interface names containing dots specially when resolvectl is
pretending to be resolvconf to fix
https://github.com/systemd/systemd/issues/20014 .
Move the special suffix-stripping behaviour of ifname_mangle out to the
new ifname_resolvconf_mangle to be called from resolvconf only.
The mount option has special meaning when SELinux is enabled. To make
NoNewPrivileges=yes not break SELinux enabled systems, let's not set the
mount flag on such systems.
This reverts commit 1753d30215.
Let's re-enable that feature now. As reported when the original commit
was merged, this causes some trouble on SELinux enabled systems. So,
in the subsequent commit, the feature will be disabled when SELinux is enabled.
But, anyway, this commit just re-enable that feature unconditionally.
This fixes repart's, systemctl's, sysusers' and tmpfiles' specifier
expansion to honour the root dir specified with --root=. This is
relevant for specifiers such as %m, %o, … which are directly sourced
from files on disk.
This doesn't try to be overly smart: specifiers referring to runtime
concepts (i.e. boot ID, architecture, hostname) rather than files on the
medium are left as is. There's certainly a point to be made that they
should fail in case --root= is specified, but I am not entirely convinced
about that, and it's certainly something we can look into later if
there's reason to.
I wondered for a while how to hook this up best, but given that quite a
large number of specifiers resolve to data from files on disks, and most
of our tools needs this, I ultimately decided to make the root dir a
first class parameter to specifier_printf().

Due to a little misunderstanding the last patch doesn't work as
expected, since test_create_image() is called only for the first image
(usually TEST-01-BASIC), and all subsequent images are then (possibly)
modified with test_append_files().
Follow-up to 179ca4d2b1.
