That's a good solution Nick, even better as Jean-Louis suggested adding 
"pfexec-path" property.

I have one more question regarding zfs in zones/containers. I want to do the 
backup from the global zone how would I accomplish that ? File systems are 
mounted relative to the root path see below:

# zfs mount | grep k

disk/k                        /zones/k/root/disk/k
disk/k/data                   /zones/k/root/data


# zfs list | grep k
disk/k              72.5K   500M  24.5K  /disk/k
disk/k@backup       23.5K      -  24.5K  -
disk/k/data         24.5K   500M  24.5K  /data
disk/k/data@backup      0      -  24.5K  -

How would I specify the disk list entry ?

thanks GG

Probably Solaris 10 Update 6 due out in approximately one month will
*probably* have ZFS rights delegation. The ZFS implementation included 
in OpenSolaris 2008.11 snapshots already have this feature.

In the mean time you can give the Amanda backup user the rights to 
manipulate ZFS filesystems by using the following command :

usermod -P "ZFS File System Management,ZFS Storage Management" 
<amanda-backup-user>

Then you will need to run all ZFS commands via pfsh or pfexec to get the 
profile assigned rights. I've attached a patch for amzfs-snapshot to do 
exactly this.

Regards,

Nick
