When DefaultInstance is set, we replace template references with
template@default-inst. But in this case we want to create a symlink for the
template name, so that systemd will fill in the instance from the
wanting/requiring unit. This is only possible for those units that actually
have an instance set, so we create the symlink only from .requires/ or .wants
of an instantiated unit (then this specific instance will be used), or a
template (than some instance will be inherited later).
Specifically:
...
[Install]
WantedBy=other@.service, fixed.service
DefaultInstance=inst
→ enable foo@.service creates other@.service.wants/foo@inst.service, and
other@a.service will want foo@inst.service, and other@b.service will want foo@inst.service,
and fixed.service will want foo@inst.service.
Without DefaultInstance,
→ enable foo@.service creates other@.service.wants/foo@.service, and
other@a.service would want foo@a.service, and other@b.service would want foo@b.service,
but enablement fails because no dependency can be created for fixed.service:

prepare_socket_bind_bpf() is called from two sites: socket_bind_supported() and
socket_bind_install_impl(). For the latter, when errors occur we certainly want
to log, since they'll be fatal for the unit. But for the former, we should be
quiet, at least on the "expected" errors like lack of permissions. I kept error
on map resizing and such, which should not fail, at log_warning(). They are not
fatal when called from socket_bind_suppported(), but still a sign that
something is off.
Currently BPF filters can only be used by privileged users. Thus each systemd
--user will fail in socket_bind_supported(). With the patch, we only log this
at debug level.

With the previous commit, we would not complain about the not-found path, but
the check is still not useful. We use a libc function to resolve the glob, and
it has no notion of treating autofs specially. So we can't avoid touching
autofs when resolving globs. But usually the glob is found in the last
component of the path, so if we strip the glob part, we can still do a useful
check in many cases. (E.g. if /var/tmp is on autofs, something like
"/var/tmp/<glob>" is much more likely than "/var/<glob-that-matches-tmp>/<something>".)

tools/analyze-dump-sort: a helper to compare two 'systemd-analyze dump' outputs
Lines in the dumps are ordered by some pseudo-random hashmap entry order, which
makes it hard to diff two outputs. This sort the entries alphabetically, and
also sorts items within the entries, and supresses timestamps and other fields
which always vary.
We could sort the output inside of systemd itself, but it'd make things more
complex, and we probably don't need output to be sorted in most cases. It also
wouldn't be enough, because timestamps and such would still need to be ignored
to do a nice diff. So I think doing the sorting and suppression in a python
helper is a better approach.
