Log message:
Use exclusive lock under /dev/, silence expected errors in installer
resolvd(8), slaacd(8) and dhcpleased(8) are different from other daemons
in that there must only be a single instance.
resolvd already does this, adjust slaacd and dhcpleased accordingly while
moving the lockfile paths under /dev/ such that they work early on boot and
don't run into races should /var be (un)mounted between daemon starts.
Locking is especially required in the installer where all three daemons are
started every time the "(I)nstall, (U)pgrade, (A)utoinstall or (S)hell? "
prompt is entered, i.e. restarting installation or dropping into a shell
and back into the prompt again would start multiple instances.
To avoid expected lockfile error messages in between installer prompts,
discard standard error when starting the autoconf daemons; none of them
has other potential failure cases in installer mode before daemon(3)izing.
