Similar in style to previous commit, let's handle these two errors
properly, i.e. as equivalent to no entries found. Let's debug log about
them, to make things either to deal with when debugging (after all
userdbctl to a large degree are debugging tools).
The lower-level userdb code will return ENOLINK if varlink lookups are
disabled explicitly and we couldn#t find an answer any other way. Let's
not propagate this to clients, since they don't have control over this
feature anyway: we decide internally when to disable varlink lookups
(e.g. if DropIn lookups are requested we disable them) and to the client
side that should not be visible: if we can't find a record with the
flags we pick then we should report then we can't find any, and that's
it.
Fixes: #21223
When using "capture : true" in custom_target()s the mode of the source
file is not preserved when the generated file is not installed and so
needs to be tweaked manually. Switch from output capture to creating the
target file and copy the permissions from the input file.

This fixes a bug[1] with some generated autostart app services which
fork and exit immediately after main application process start,
that caused them not to launch during session startup, as the entire
cgroup was immediately killed by systemd.
This can also happen with apps such as file browsers, whose initial
process will exit after the window is closed, but who intend to leave a
daemon child running.
Since the forking model of a .desktop application cannot be known at
service generation time otherwise, ExitType=cgroup is the only effective
way to fix this bug.

This introduces `ExitType=main|cgroup` for services.
Similar to how `Type` specifies the launch of a service, `ExitType` is
concerned with how systemd determines that a service exited.
- If set to `main` (the current behavior), the service manager will consider
the unit stopped when the main process exits.
- The `cgroup` exit type is meant for applications whose forking model is not
known ahead of time and which might not have a specific main process.
The service will stay running as long as at least one process in the cgroup
is running. This is intended for transient or automatically generated
services, such as graphical applications inside of a desktop environment.
Motivation for this is #16805. The original PR (#18782) was reverted (#20073)
after realizing that the exit status of "the last process in the cgroup" can't
reliably be known (#19385)
This version instead uses the main process exit status if there is one and just
listens to the cgroup empty event otherwise.
The advantages of a service with `ExitType=cgroup` over scopes are:
- Integrated logging / stdout redirection
- Avoids the race / synchronisation issue between launch and scope creation
- More extensive use of drop-ins and thus distro-level configuration:
by moving from scopes to services we can have drop ins that will affect
properties that can only be set during service creation,
like `OOMPolicy` and security-related properties
- It makes systemd-xdg-autostart-generator usable by fixing [1], as obviously
only services can be used in the generator, not scopes.

After commit c3dead53d5 the test can fail
if the procfs file(s) aren't writable, because the check for permission
failure happens after a call that will never fail, since setting the
limit to the existing limit will always pass.
This also refactors the function slightly to make the test var names
clearer.
This entry only matches on vid/pid, so the pen event node of the device
would also get assigned the ID_INPUT_TABLET_PAD property - making it
break with libinput.
On top of that, UC-Logic's tablets re-use USB ids, so now we're breaking
multiple devices this way.
To get this device tagged correctly, use libwacom which has the
per-device hwdb entries.
