so as a summary of this thread:

   - rename halt.c to shutdown.c and fix Makefile.am linking it to
core as it is not needed.
   - replace getopt with strcmp of verbs: poweroff, reboot, halt
   - sigtimedwait() + waitpid(WNOHANG) as replacement for alarm()
   - remove sync()
   - umount swap after others
   - exec kexec before trying reboot action.


do we have a consensus over:
    - handling of devicemapper?
    - umount loop? shouldn't be required...
    - waitpid() after SIGKILL
    - is SIGSTOP -> SIGXYZ -> SIGCONT required?
