Question on INST and disk setup - massiverobot - 11-08-2018
Setting up Irix 6.5 - one thing I found confusing.
When inst is asking to setup the disk - it looks like you can pick
rootdisk
userdisk
optiondisk
- which seems to correspond to / , /usr and /opt?
But selecting each one seems to overwrite the current disk (dsk0).
Do you need to have 3 disks and set each one up for root, usr and opt?
I'm pretty familiar with setup and partitioning for Linux- and normally you setup the partitions on the disk you have, Inst seems to be doing it very differently.

I believe it is not inst which presents you this option, but fx, the disk partitioning tool.
IRIX disks have a volume header which associates partitions with certain volume numbers. In fx you can choose to have a root file system on one partition on the disk, or choose a 'usrroot' configuration where / and /usr are on separate partitions. I forgot the exact volume numbers, but i believe they are 1 for root and 6 for usr. The third choice 'opt' will partition the disk with a single partition with i believe number 7.
The numbers are used for inst to mount the partitions later on in the installation and write it to /etc/fstab in the IRIX filesystem.
In practice for single disk systems nobody is using 'usrroot' anymore, so choosing 'root' is fine. 'opt' is only useful for having a second disk with stuff which is not part of the IRIX OS.
