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
zfs snapshot zones/[EMAIL PROTECTED]
zoneadm -z $zone attach -u
if [ $? != 0 ] ; then
zfs rollback zones/[EMAIL PROTECTED]
Of course, it would be nice if zoneadm would just do this on its own.

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.
