* d/t/upstream: capture new merged 'system.journal' from tests.
https://github.com/systemd/systemd/pull/15281
* d/t/upstream: use --directory or --file param for journalctl.
Properly tell journalctl if the journal to parse is a dir or file.
* d/t/storage: check for ext2 or ext4 fs when using crypttab 'tmp' option.

* debian/tests/localed-locale: Fix for environments without en_US.UTF-8.
Unconditionally back up/restore locale configuration files and generate
en_US.UTF-8. Previously the test failed in environments which have some
locale other than en_US.UTF-8 in /etc/default/locale.
Also fix the assertion of /etc/locale.conf not being present after
localectl. This only applies to Debian/Ubuntu tests, not upstream ones.

* 40-vm-hotadd.rules: check offline before onlining memory/cpus.
The kernel will return EINVAL if the memory or cpu is already online,
which is harmless, but adds a confusing error to the log. Avoid the error
message by only onlining if the memory or cpu is currently offline.

Bug description:
[impact]
systems using cryptsetup-based encrypted swap may hang during boot due
to udevd missing the notification that swap has been setup on the
newly created swap device.
[test case]
see original description, and reproduction is intermittent based on
timing
[regression potential]
any regression would likely occur during, or after, boot when creating
an encrypted swap device and/or while waiting to activate the new swap
device. Regressions may cause failure to correctly enable swap and/or
hung boot waiting for the swap device.
[scope]
this was (potentially) fixed upstream with PR 15836, which is not yet
included in any upstream release, so this is needed in all releases,
including groovy.
also note while the upstream bug is closed, and code review seems to
indicate this *should* fix this specific issue, there are some
comments in the upstream bug indicating it may not completely solve
the problem, although there is no further debug of the new reports.
[original description]
On some systems, cryptsetup-based encrypted swap partitions cause
systemd to get stuck at boot. This is a timing-sensitive Heisenbug, so
the rate of occurrence varies from one system to another. Some
hardware will not experience the issue at all, others will only
occasionally experience the issue, and then there are the unlucky who
are unable to boot at all, no matter how many times they restart.
The workaround is for the cryptsetup-generator to generate cryptswap
service entries that call `udevadm trigger` after `mkswap`. This will
ensure that the udev event is triggered, so that systemd is notified
that the encrypt swap partition is ready to activate. This patch has
already been submitted upstream to systemd, but it was not accepted
because it is a workaround for the side effect of systemd not seeing
the udev event upon creating the swap partition.
