Almost everyone wants kmod support, so don't fail silently if the libs are
out-of-date.
kmod can still be explicitly disabled and if it is not found at all, we still
default to disabling it.
As of kmod v14, it is possible to export the static node information from
/lib/modules/`uname -r`/modules.devname in tmpfiles.d(5) format.
Use this functionality to let systemd-tmpfilesd create the static device nodes
at boot, and drop the functionality from systemd-udevd.
As an effect of this we can move from systemd-udevd to systemd-tmpfiles-setup-dev:
* the conditional CAP_MKNOD (replaced by checking if /sys is mounted rw)
* ordering before local-fs-pre.target (see 89d09e1b5c)
During re-execution and shutdown cgroups agents might not be able
to connect to systemd's private D-Bus socket, the printed error to
the console is misleding in that case, so turn it into a warning.
During shutdown, when we try to clean up all remaining processes, the
kernel will fork new agents every time a cgroup runs empty. These
new processes cause delays in the final SIGTERM, SIGKILL logic.
Apart from that, this should also avoid that the kernel-forked binaries
cause unpredictably timed access to the filesystem which we might need to
unmount.
RPM macros are moved from /etc to /usr, in the sprit of moving
in the direction of empty /etc.
RPM gained support for the new directory recently, in v. 4.10.90:
https://bugzilla.redhat.com/show_bug.cgi?id=846679.
The affected files in this patch had inconsistent use of tabs vs. spaces
for indentation, and this patch eliminates the stray tabs.
Also, the opening brace of sigchld_hdl() in activate.c was moved so the
opening braces are consistent throughout the file.
The kernel adds those when the file is deleted,
but we don't really care if the file is still there
or not. The downside is that if the filename ends
in ' (deleted)', this part of the filename will be
removed. Too bad.
Use proper grammar, word usage, adjective hyphenation, commas,
capitalization, spelling, etc.
To improve readability, some run-on sentences or sentence fragments were
revised.
[zj: remove the space from 'file name', 'host name', and 'time zone'.]
Since we should allow registering/unregistering transient units with the
same name in a tight-loop, we need to make the GC more aggressive, so
that dead units are cleaned up immediately instead of later.
hence, execute the GC sweep on every event loop iteration and clean up
units. This of course, means we need to be careful with adding units to
the GC queue, which we already are since we execute check_gc() of each
unit type already when adding something to the queue.
