The way I normally do this is to (in the global zone) symlink /usr/perl5/mumble to somewhere that would be writable such as /opt, and then put what you need into that location in the zone. Leaves a dangling symlink in the global zone and other zones, but that's relatively harmless. -- -Peter Tribble http://www.petertribble.co.uk/ - http://ptribble.blogspot.com/ _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
