/usr and AdvFS

Dear Managers:

I have the following setup in /etc/fstab:

/dev/rz3a / ufs rw 1 1
/proc /proc procfs rw 0 0
/dev/rz3b swap1 ufs sw 0 2
/dev/rz3d /var ufs rw 1 2
/dev/rz3g /usr ufs rw 1 2
advfs_domain#users /users advfs rq,userquota,groupquota 1 2
advfs_domain#tex /Tex advfs rq,userquota,groupquota 1 2
advfs_domain#local /usr/local advfs rq,userquota,groupquota 1 2
                 .
                 .
                 .

The advfs_domain spans two volumes, /dev/rz3h and /dev/rz8c. I am
getting a new disk and would like to take the opportunity to change
my set up to the following (i.e. rz3 will then be partitioned as
a,b,g and /dev/rz3g will be added to the advfs_domain):

/dev/rz3a / ufs rw 1 1
/proc /proc procfs rw 0 0
/dev/rz3 swap1 ufs sw 0 2
advfs_domain#var /var advfs rw 1 2
advfs_domain#usr /usr advfs rw 1 2
advfs_domain#users /users advfs rq,userquota,groupquota 1 2
advfs_domain#tex /Tex advfs rq,userquota,groupquota 1 2
advfs_domain#local /usr/local advfs rq,userquota,groupquota 1 2
                 .
                 .
                 .

The point is that I want to get away from the traditional ufs
restrictions of fixed partition sizes and be able to change the size
of /usr (or /var or whatever) as the need arises within the restriction
only of my total available disk space, i.e. the advfs_domain. I would
very much appreciate any comments from people who have experience, good
or bad, with this type of arrangement, in particular, with including the
usr and var filesets within a general domain, along with users, etc.
Can anyone think of any compelling reason not to do this?

Thanks in advance,
