Package: casper
Version: 1.63+debian-2
Severity: normal
Tags: patch
The correct parameters are stillnot being given to the unionfs mount command
when an NFS root is used.
This patch detects the filesystem of a directory and passes the correct
argument "nfsro" to the unionfs
mount in rofsstring in then event of the directory being on NFS.
NB: patch is to casper script for version 1.63+debian-2
Regards
Alex Owen
