[PATCH 1/2] Unmount filesystems before shutdown or reboot on s390x (#605577)

[David Cantrell <dcantrell redhat com>]

Prevents unclean root filesystem on first reboot.  On all platforms but
s390x, this is handled by the unmountFilesystems() function in
loader/undomounts.c, but since init on s390x is a shell script, we need
this forced umount call.
