If the root file system requires manual attention then
rc.sysinit invokes sulogin to allow the superuser to
correct the problem.  When sulogin returns rc.sysinit
attempts to reboot the system, but it invokes reboot
without the -f option so reboot tries to run shutdown which
tries many things which break because (a) they were never
started in the first place or (b) / is a read only file
system.  This causes confusion.  This reboot should be
invoked with -f . This problem affects initscripts-4.16-1.
rc.sysinit line 108.
