What? When you mount a filesystem, nothing should be written to it
except atime info. You should mount it with "ro" though unless you have
a pressing need to write to it.

"Drive ID"? Do you mean "partition ID"? If this is a SCSI disk and
you've set the disk to have the same ID as another SCSI device in the
chain, then nothing will work properly. If you meant "Solaris
filesystems use 0x82 as a partition ID", then that means nothing. Linux
doesn't use the partition ID bytes for anything at all. Filesystem
detection is done by reading the first sector and looking for magic
numbers, or done with the -t option to mount.

Nope.
/dev/?? /mnt/somewhere ufs ufstype=sun,ro defaults 1 2
Only / gets 1 1 , you should use "ro" if you think the disk is being
written to, and are you sure that "sun" is correct? That's for Solaris
filesystems that were made on a Sparc. Solarisx86 filesystems use
"sunx86". If the filesystem was originally made on a Sparc, you will
probably need to recompile your kernel and make sure that File Systems->
Partition Types->Advanced Partition Selection and Sun Partition Table
Support are both Y. This is *never* set to Y by default on an x86.
You'll probably have to reboot after recompiling.
After you boot with the proper partition table support built in to the
kernel, you'll see something like this in dmesg:
Sun disklabel <sda1 sda2 sda3 sda4 sda5 sda6 sda7 sda8>
...and you can try mounting each one in turn. Make sure you use ro!
> Do I need to add UFS filesystem support into my kernel?
No, it will be just fine to have it as a module. If you're using a
stock kernel, it'll probably be there already; if not, File Systems->UFS
Filesystem Support, say "M", make modules modules_install. HTH,
