I've been mucking around with 7.4.1 this week now that it's turned up
silently in EMC's usual style...
 
One thing I've noticed immediately is that the All savesets option on
Solaris 10 clients now enumerates zfs filesystems even if they are not
in vfstab - although the NMC doco still says it won't backup zfs unless
they are listed in vfstab.
 
What they've done to make it work is a bit broken as it's also showing
up zfs filesystems in zones in the probe (usually these are hidden from
df output in the global context). However  the resulting backup size for
these filesystems is 0KB because they really are not mounted globally.
 
It still doesnt ignore /system/object and /system/contract either.
 
i had a look at savefs with truss and the probe all function is parsing
the data from /etc/mnttab  to get the list of filesystems  which means
they have all the information needed, they just haven't coded it well.
 
so 1 step forward, 2 steps back...    as usual.
