If systemd-nspawn is newer than the running systemd, we might try to set
CoredumpReceive=yes when systemd doesn't know about it yet. Try and
check if the running systemd is aware of this setting, and if not, don't
try and use it.

("nspawn: set CoredumpReceive=yes on container's scope when --boot is set").
Let's support the same filtering options that we also support in
udevadm trigger in udevadm info to filter the devices produced by
--export-db.
One difference is that all properties specified by --propery-match=
have to be satisfied in udevadm info unlike udevadm trigger where just
one of them has to be satisfied.
Instead of mounting over, do an atomic swap using mount beneath, if
available. This way assets can be mounted again and again (e.g.:
updates) without leaking mounts.
almost all code in namespace.c only logs at debug level as it is
"library-like" code. But there are some outliers. Adjust them to match
the rest of the code
(Well, there are some left)
frankly, the log message shouldn't be there at all, but the error path
be propagated up, with a recognizable error code. But apparently this is
important to @bluca.
So far we calculated exactly how many mounts we will generate, which is
a bit fragile, and easy to get wrong.
Let's normalize this, and grow the array of mounts as we need.
Various other modernizations while we are at it, such as FOREACH_ARRAY
usage, or `_cleanup_` usage.
UKIs may be loaded in a way, that there can not be a device handle to
the filesystem, that contains the image, for example when using a
bootloader to load the image from a partition with a file system that is
not supported by the firmware.
With the current systemd stub, this causes a failed assertion, because
stub gets passed a NULL DeviceHandle and FilePath. Inserting two
explicit checks enables proper boot even in this case.
Fixes: #29331
According to RFC 6762 section 8, an mDNS responder is supposed to announce its
records after probing.
Currently, there is a check in dns_scope_announce which returns if there are any
pending transactions. This prevents announcements from being sent out even if there
are pending non-probe transactions.
To fix this, return only if there are active probe transactions.
Before this we'd fail with a complaint that PIDFDs is not supported by
the service manager. Add some compat support by falling back to classic
numeric PIDs in that case.
