Binary package hint: initscripts

When umounting NFS (or networked filesystem) dirs, other "dependent
dirs" have to be unmounted as well. This includes all the dirs below an
NFS dir and all dirs which are loops over files which are mounted below
an NFS dir. The following patch attempts to correct somewhat the
situation. It is not perfect because losetup does not show the complete
filename of a loop device, but the filename that was indicated to the
kernel at loop creation.
(sorry for the borked patch, but I don't know how to attach)
