[9fans] Linux / Plan9 cohabitation...

[Keith Rhodes]

I intend to install Plan 9 on my twin Celery. I've been running Linux for a
little over three years, and have been following Plan 9 from a safe distance; I
feel it's time for me to grab hold of it now.

Here's the setup I plan to use, but I don't know how feasible it is...
especially the ides of having the Linux swap partition on the physical disc used
for Plan 9, and the Plan 9 swap on the physical disc used for Linux... can these
partition types cohabit?

The reasoning is to try to keep discs that will frequently be accessed
simultaneously on separate IDE controllers, as I believe this will give a
performance improvement.

I'll try to use standard Linux terminology here...

The IDE[0-3] numbers represent the controllers on the ABIT BP6 motherboard.
The devices /dev/hd[a-f] are the whole discs devices.

IDE0 /dev/hda   6.4GByte     Linux kernel and most of file system
                             Plan 9 swap partition

     /dev/hdb   CD-Rom drive


IDE1 /dev/hdc   2.5GByte     Plan 9 kernel and most of file system
                             Linux swap partition

     /dev/hdd   empty

IDE2 /dev/hde  10.8GByte     Home directories, Applications,

     /dev/hdf   empty

IDE3 /dev/hdg   empty

     /dev/hdh   empty

So, is it possible to create a swap partition for one OS, on the same physical
disc as the main partition for the other OS?

Yes, with a caveat.  Plan 9 does not support
the use of extended partitions -- it needs its
own primary partition for each piece of disk
you'd like it to control.

I'd suggest setting up the Plan 9 kernel and
swap on the same disk to start with, and then
once you have things set up, manually create
the new swap partition where you really want it.
