During fresh install time there is no root directory or opt directory, 
just the /dev/sd* partitions to deal with. The partition I keep /opt on 
I exclude and only format the partition to become the root directory, 
which is the same partition it was before, to install to.

After install, I hand edit /etc/fstab to auto-mount it the /opt 
partition right over the empty one that was freshly created. I also keep 
my /opt filesystem on ext3, so I'm not diddling with the ext4 
complexities. So, if I unmounted the /opt partition, there is still an 
/opt directory, yes.

Using ext3 all I have to add to fstab is:
/dev/sda2	/opt	ext3

I like simple. I think I need to add the filesystem check bit. :) Ric
