[Casper] Upgrading from Tiger to Leopard

When we did our massive dual boot image over this last summer I was looking at the /etc/fstab file to hide the windows partition from the OS X side. I had so many problems getting fstab to work. It would not work for me if I used volume name or the device mount point, ie /dev/disk1s3/. It would work if I used UUID, but if you mass duplicate that UUID to tons of machines I found that it wouldn't work.
What has been your experience using /etc/fstab in 10.5?

He he, thought that'd be popular.
The script is fairly poorly written (I'm not a Bash wiz) so any
improvements are welcome (please let me have any so I can improve mine).
We run it as a 'before' script during our imaging process and it
takes a look at the internal disks, tries to figure out which is the
system disk or otherwise the disk in the first bay (Mac Pros only I
think) and then partitions it up into various volumes that we want.
Our post-flight script then takes the names of these and builds an
fstab file which it writes down to /etc. It also moves our admin
user's ('lwsadmin' in the script) home directory to /var/homes. We
figured this may be wise just in case the data partition goes dead
for any reason. Our OS image is pre-confd with lwsadmin's home
pointing at the correct location, so you may want to excise this
section and rely on using root to login in bad circumstances.
Oh, the post script also 'hides' some of the partitions (Restore,
Freespace etc) so they don't show on the desktop, check the resulting
fstab to see how this is done.
Be careful using this, it is destructive. Usual disclaimers apply =)
