There is a whole theory of how to partition a disk :)
Here is what I have (spread across 2 disks) on blake:
blake[12:37pm]:~>df
Filesystem 1024-blocks Used Available Capacity Mounted on
/dev/hda1 15856 11910 3116 79% /
/dev/hda3 1189542 572591 555489 51% /usr
/dev/hda4 726443 453013 235908 66% /opt
/dev/hdb1 63885 18 60568 0% /tmp
/dev/hdb2 127361 77443 43341 64% /var
/dev/hdb3 634724 421568 180371 70% /var/spool
/dev/hdb4 385923 236517 129473 65% /home
As my /usr is quite large, putting swap towards the middle of the disk
would have meant putting it in the 2nd half of the disk, so I opted to put
swap between / and /usr (swap is hda2).
If I had to put them all on one disk (which would necessitate logical
partitions, which I persoanlly detest :) here is the order I would use:
/
/tmp
SWAP
/usr
/opt
/var
/var/spool (This could of course easily be kept as part of /var).
/home
/ is at the start of the disk for speed reasons.
/tmp needs to be in a fast spot for good system performance.
SWAP The idea here is that as the drive head is flying between different
partitions it shoudl pass over the swap partition and be able to read
and write stuff there before going on its way.
/usr should be in a fast spot on the disk (towards the beginnning) as it
contains alot of stuff you want to be able to load quickly (system
bins, daemons,etc).
/opt has a similar function to /usr but doesn't contain 'system' stuff so
gets to sit just behind /usr.
/var could use a reasonably fast spot too, so gets to be next.
/home should be on the slowest part of the disk, as speed is not such an
issue here.
I hope this helps.
Cheers,
-Robert
