The combination of update on attach plus zones on ZFS should make this problem be one that isn't too scary. I imagine the following as being standard practice. zfs snapshot zones/[EMAIL PROTECTED] zoneadm -z $zone attach -u if [ $? != 0 ] ; then zfs rollback zones/[EMAIL PROTECTED] fi Of course, it would be nice if zoneadm would just do this on its own. > One thought with 2) is to also consider -P filename, where filename > lists the patches or packages. Similar to -x and -X for flarcreate. The only reason I would say not to use another option is to keep the option free for other things in the future. I think that the IDR situation will be rare and the probability that a lot of IDR's exist on a single system is quite unlikely. Assuming that the Indiana/OpenSolaris approach to packaging is integrated as the replacement for current packaging+patching then this functionality will not really be needed post S10 and as such also suggests that keeping the option free for something else may make sense. If I am wrong about the likelihood of having a longish list of patches to ignore, then I think the -P option makes sense. -- Mike Gerdts http://mgerdts.blogspot.com/ _______________________________________________ zones-discuss mailing list zones-discuss@opensolaris.org
