I just like to add that using separate filesystems lets you mount them
with different options. For example, I mount all filesystems other
than / with option nodev, and all filesystems other than / and /usr
(maybe /usr/local) with noexec. This makes it harder for malicious or
inquisitive users to run their own software or play other tricks on the
system.
Also, on mail servers, I use a separate filesystem for the mail spool,
and mount it with option data=journal, effectively forcing synchronous
behaviour. This is not ideal for performance but good for reliable mail
handling.
Cheers
Steffen.
