Its a major advantage to me in my current work enviroment, it also simplifies how things look on various machines across the network when we export out /usr again, also when we roll out new software that resides in /usr on the network if we fill up partitions we don't break more than we need to. You can then also mount /usr readonly so that when your box crashes you don't have to fsck the filesystem as it should be consistent so you only have to fsck / which should take less time.
Disadvanatges of separate filesystems for / and /usr would include a reduced set of facilities available if you boot without mounting non-root filesystems and a greater chance of running out of space on one of them.
but why would you not mount one at boot? this would only happen if you had a filesystem error and nothing should write to /usr in normal operation so nothing should use any diskspace in the /usr heirachy up and not dead because of an error under /usr which fsck can't fix.
(I set mail-followup-to for a reason, BTW.)
sorry didn't mean to do that, it appears mozilla mail doesn't obey such things correctly then. I wouldn't run mozilla-mail but due to brain dead mail admins I can't change that, I have to run a brain dead mail client at work :(
