I can mount the CDROMs, images of the CDROMs, hard drives ... whatever.
As far as netinstall goes, I either loop-mount the CD images and
NFS-export them, or I mount and copy everything off of them and export
that. I suppose if I had all the install stuff on an EFS-formatted
disk, it wouldn't be much trouble to pull it out of an SGI and mount it.

Well, Linux also has support for SGI partition tables ... or, you could
toss the mount option seek=x blocks if you know where the partition
you're looking for starts (and you don't have SGI partition table
support compiled into your kernel). This works fine with both CDs and

Um ... no? Block device is a block device is a block device. If it's
EFS-formatted, it doesn't make much difference to the Linux EFS support.
Not that I've ever heard of EFS on a USB stick ...
