I was thinking the other way around actually. If /boot were to get messed up,
it wouldn't affect /.

Well, I'll be using Cyrus IMAPd. Doesn't use Maildir, but does create separate
folders per user. Thus, the spool is really not going to hold data much.
However long it takes to rip data off incoming (using postfix) and send it out,
or however long to hand it off to lmtpd and let cyrus deliver it.

Oh. Guess I didn't quite understand how disk I/O functioned. I figured
something like /var, which will have a lot of synchronous writes, would get
better performance outside of / or /home.

Just from a performance point of view or for other reasons?

Once again . . . just for stability? security?

RC> RAID has no relevance to the issue of partitioning in this sense.
Well, my point here was, with the RAID 10, I already have a pretty good amount
of reliability, as if one drive fails, the system can still function. And with
disks that are pretty reliable to begin with, I wasn't sure if the combination
of all these would merit just one large / fs.
Thanks again.
