Charles Anderson posted an example on the list a while back and it worked
for me - use VIRTUALMOUNTPOINT for each ext3 filesystem.  ext3 isn't
supported in TSM yet.

For your system, in dsm.sys:

VIRTUALMOUNTPOINT  "/"
VIRTUALMOUNTPOINT  "/boot"
VIRTUALMOUNTPOINT  "/boot2"
VIRTUALMOUNTPOINT  "/root2"
