I'm about to make a heterogenous cluster with an 835 as server and
mainly 340:s as clients.

While reading the manual I found to my surprise that when using an 800
as server for 300:s, you must have the root partition on section 13
of your primary disk and only three partitions (boot, swap and / I presume).
If not, reinstall 7.0.

Why is this? It doesn't make sense. Is it only so that the root partition
is big enough to hold the 300 OS as well (13 is one of the biggest sections),
or is it something more to it? I can't see any logical reason behind it.
The manual doesn't explain anything, it's the "Don't ask, do as you are told"
attitude.

What I wanted to do was set up the 835 as a cluster server, install the
300 software my self, setting up CDF:s manually, and add clients.
This will save me a lot of time since I don't have to move filesystems
about and repartition disks. Needless to say I don't have the root partition
on section 13.

If anybody knows anything about this or has experience of heterogeous clusters
please let me know if the world will end if I ignore the section 13 thing.

Comments and general experiences with heterogenous clusters are also greatly
appreciated.

Thanks in advance,
