This is what I did for SLES8: /dev/system/root 132M 92M 41M 70% / /dev/dasdb1 24M 6.3M 16M 29% /boot /dev/system/home 3.0G 33M 3.0G 2% /home /dev/system/opt 384M 97M 288M 26% /opt /dev/system/usr 2.5G 1.4G 1.1G 56% /usr /dev/system/var 96M 68M 29M 71% /var
In my case I used 3 disks and then used LVM to manage them but they could easily be separate devices. The /boot device is an ext2 partition of a minidisk from which we IPL.
