i think this is not enough for "ALT+PRINT+K" because sync
is only for flushing disk-buffers, maybe i play around a
little bit at the weekend but i guess we need something
like 4 + 64 for "ALT+PRINT+K" and 16 is really nice if
all hangs to use it before a hrad power-cycle

what i nat want are the reboot/halt-options because without
sync/umount they are the same like a hard-reset/power-cycle
