Patch resolves the problem that 'systemctl is-enabled' does
not work for templated units.
Without this patch, systemctl is-enabled something@abc.service
returned "No such file or directory", because it first checked
if /usr/lib/systemd/system/something@abc.service, etc. exists.
If systemctl is-enabled is called for templated units, this
check should be omitted and it should search for symlinks in
the .wants dirs right away.
This patch fixes the broken behaviour and resolves
https://bugs.freedesktop.org/show_bug.cgi?id=55318.
[zj: fixed the patch to still check for broken symlinks and
masked instances. Also removed untrue assumptions from
the patch description.]
Just calling service_enter_dead() does not kill any processes.
As a result, the old process may still be running when the new one is
started.
After a watchdog failure the service is in an undefined state.
Using the normal shutdown mechanism makes no sense. Instead all processes
are just killed and the service can try to restart.
This change is based on existing usage in systemd and online.
'File-system' may make sense in adjectival form, but man pages
seem to prefer 'file system' even in those situations.
We want to allow clients to process an sd_bus_message on a different
thread than it was received on. Since unreffing a bus message might
readd some of its memfds to the memfd cache add some minimal locking
around the cache.
We need this since we might need to invoke the release ioctl for
messages. Since we don't want to add any locking for that we simply keep
a reference to the bus and then rely that the fd stays valid all the
time.
That way ordering it with MountsRequiredFor= works properly, as this no
longer results in mount units start requests to be added to the shutdown
transaction that conflict with stop requests for the same unit.
This brings the check for ENABLE_GTK_DOC in line with
HAVE_INTROSPECTION and other similar checks. Only
the status line that is printed with uninstalled
gtk-doc is changed.

This allows us to guarantee that the first payload_vec we pass to the
kernel for each message is guaranteed to include the full header and all
its field.
