We know that launching a unit will fail if some required directories
haven't been mounted yet. There's no point in starting it just to
have it fail even before it gets a chance to run.
It would fire just once.
Also fix units from sec to usec as appropriate.
Decrease the switching interval to 1/3 s, so that when the time
remaining is displayed with 1s precision, it doesn't jump by 2s every
once in a while. Also, the system is feels noticably faster when the
status changes couple of times per second instead of every few
seconds.
Produces output like:
[ *** ] (1 of 2) A start job is running for slow.service (33s / 1min 30s)
The first nubmer is the time since job start, the second is the job timeout.
The cppcheck target was introduced by commit 16f4efb415
"build-sys: add cppcheck target". But it is preferable to use a make phony target
for it, as this patch does.
There are two general reasons to use a phony target: to avoid a
conflict with a file of the same name, and to improve performance. In
this case the first reason is obvious, and the second is that make
skips the implicit rule search for phony targets, since it knows that
phony targets do not name actual files that could be remade from other
files (as described in the "Gnu Make" Manual).
Debian recently introduced the option key-slot to /etc/crypttab to
specify the LUKS key slot to be used for decrypting the device. On
systems where a keyfile is used and the key is not in the first slot,
this can speed up the boot process quite a bit, since cryptsetup does
not need to try all of the slots sequentially. (Unsuccessfully testing
a key slot typically takes up to about 1 second.)
This patch makes systemd aware of this option.
Debian bug that introduced the feature:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=704470
A compatibility libsystemd-login library is created which uses
.symver and ifunc magic proposed by Lennart to make programs linked
to the old library name continue to work seamlessly.
Unfortunately the bfd linker crashes:
https://sourceware.org/bugzilla/show_bug.cgi?id=16467
This will be fixed in binutils 2.25.
As a work-around, gold can be used:
LDFLAGS=-Wl,-fuse-ld=gold
Unfortunately the switch to pick the linker appeared in gcc 4.8.
This also doesn't work with LLVM:
http://llvm.org/bugs/show_bug.cgi?id=11897
gold doesn't exhibit the problems with linking of compatibility
libraries.
It is also slightly faster:

This works around the goa daemon crash:

This brings the calls into similar style as the respective functions in
libsystemd-journal, and also is a bi shorter and more descriptive since
it clarifies the time unit used.
