I also do it to aid in backups ... So since /, /home, /usr,
/windows (a partition I use samba to serve to windows machines), and
/tmp are all on seperate partitions, it's really easy to store each to
a seperate tape and to exclude /tmp altogether ... That, and I've been
told it's safer since if a section of your hard drive goes bad, it's
less likely to effect all your partitions, but rather only the partition
that has the bad sectors. Is there any truth to that? I remember on an
older system something in my /usr partition got hosed ... some
/usr/local
dir would crash the system if you went in there, but since /usr was on a
seperate partition I could just umount it and copy the rest of my stuff
to another computer.
