When an administrator installed a custom keyring under /etc,
signature verification selected it instead of the vendor keyring
under /usr. That could make vendor-signed system updates stop
verifying after adding local keys.
Collect all readable default keyrings, including the current and
legacy /etc paths, and pass temporary copies to GnuPG with
separate --keyring options. Keep SYSTEMD_OPENPGP_KEYRING as an
explicit override, add regression coverage for keyring
coexistence, override behavior, and current-path signing, and
silence the expected shellcheck false positive in the test
cleanup helper.
Closes: #40702
Found using linkchecker.
For virtiofsd, the man page is maintained upstream, but doesn't seem to be
available in any of the usual places. So let's link to the Debian version.
systemd.filter I have no idea what it is.
The format is not specific to gpg, it's defined by the pgp
protocols. Lintian even warns about it:
systemd-container: openpgp-file-has-implementation-specific-extension [usr/lib/systemd/import-pubring.gpg]
Rename it accordingly, as new pgp implementations are slowly becoming
more popular.
Keep using /etc/systemd/import-pubring.gpg for backward compatibility.
This also replaces the Fedora download example with another one from
Ubuntu, since Fedora's images these days no longer qualify as DDIs, they
have no distinctive partition type UUIDs set for multiple of their
partitions, hence the images cannot be booted. A bit sad. Let's provide
a command that just works in its place.
