It might be possible with care. I doubt if solaris will be able to
handle Linux file systems. In Linux, you need to configure the kernel
with
CONFIG_UFS_FS=y
but I seem to recall that if you do this and mount such a file system,
if you don't use it read-only, your results will be unpleasant. Others
will have more current information.

Sun hardware. Slice 3 (/dev/[sh]da3) must be the entire disk, for
example:
Device Flag Start End Blocks Id System
/dev/sdb1 0 22 31779 83 Linux native
/dev/sdb2 u 22 698 976482 82 Linux swap
/dev/sdb3 u 0 24620 35563590 5 Whole disk
/dev/sdb4 698 24620 34555329 83 Linux native

(second disk on one of my systems.)

Just a quick note, Solaris numbers slices starting with 0, so, under
Solaris, slice 2 is the whole disk. Just something to keep in mind if
you're in Solaris looking at disk slices.

It's certainly possible, but it won't be the easiest thing. To make
life a little saner, I recommend using 1 big root partition, because
it's a lot harder to forget which partition is which that way :)

Do something like:

/dev/hda1 - solaris /
/dev/hda2 - common swap
/dev/hda3 - whole disk
/dev/hda4 - linux /

Partition and install with Solaris, and make sure it runs. Install
Gentoo on hda4, and setup SILO to load linux off of hda4 and Solaris
off of hda1. The example silo.conf has details on how to boot a
Solaris partition.

It's possible to compile ufs support into the kernel, and with 2.6.15
I had no read/write problems. However, I was unable to ever get the
Debian ufs.fsck to build properly, so if the ufs partition needs a
fsck done, you won't be able to mount it rw.

HTH,
Mike

Mike etal.
i appreciate the suggestions and the reminder that the slice numbering
starts with 0, making the "whole disk" hda2. i plan to do some
experimentation when my schedule loosens up. i'm really curious to see
if sol10 can run some of the linux-compiled software. i can't imagine
it'll do it with no problems, but who knows ...

-- thanks, TT
