Add support for setting of initial state of NumLock. Supported values
are "yes", "no" and "bios" (on x86 platforms).
It sets NumLock in virtual consoles. If NumLock should be turned on, it
also creates empty /run/numlock-on, which can be used e. g. for setting
of X session default.
This ports a feature that exists for a long time in SUSE to systemd.

my objections start here ;)
Why do we need a third party binary for an operation that could be done
with single ioctl(0, KDSETLED... ?

huh, there is no error handling here..

There is a touch function defined in util.h for that.,.
