Q: NeXTStep v. 3.3 shows the fstype of its filesystem as 4.3. How do I make Linux mount it?

A: NeXTStep should use the UFS filesystem. You should be able to mount the partition, as we compile in the filesystem as a module. I'm not sure how long it's been supported in the 2.0.x line, but it is in 2.0.36. The 2.1.x/2.2.x line has read/write support for UFS, while 2.0.x has read-only support. It might be worth your while to wait a week for 2.2.0, or grab a 2.2.0-pre .

Try this:
modprobe ufs
lsmod (check that it's there)
mount -t ufs /dev/??? /???

Keep in mind that we never tried this, nor do we support it. I'm unsure of the stability of the driver. So, use at your own risk.

[Update a/o December 1999: The various BSD-derived Unixes are notorious for implementing the UFS filesystem differently, so check your results carefully before writing to such a filesystem from Linux. One specifies which of the numerous sub-variants get to use for mount operations using a "ufstype" additional option, e.g., "-t ufs -o ufstype=openstep" — which is probably the correct incantation for NeXTStep's and Apple Macintosh OS X's UFS volumes.]
