#  This script works by

#	   make any file system modifications
#   2. if pkgcond does not exist it works by using the older FCS logic in CheckZones()

#	   based on whether /usr/java/jre/lib is writable

#  Basically local zones can have any arbitrary directory readonly or writable
#  So a script that needs to modify say /usr/java needs
#  to figure out if this is actually doable first.
