I suspect this is too late, but:
1. Boot the upgrade tape
2. Select "Restore individual partitions"
3. Restore / and /usr; Don't restore /files.
4. exit to single user shell
5. mount your old /files somehere.
* go look at it
* several places ( cluster, spool, var?) will be directories
named sun386.sunos4.0.0 (approx., obvious)
* delete them ( rm -rf ...)
* umount the disk
6. Somewhere on the ramdisk you are working from is the script that does
the work. Maybe /usr/etc. The script is in all uppercase, some name like
UPGRADE, or INSTALL.
[ I'm sorry, I've DONE this, it works, but to find the actual name I'd
have to shut down my node, boot the installation tape, and check. I can't
do that.]
7. edit the script. Look for the case where it does the /files system.
Delete the line where it does a 'newfs' on the /file disk.
8. Make sure the application tape is in the tape drive. Execute the script
you modified in (7). Say n to / and /usr, Say y to the /files prompt.
Variations on this are possible, but I haven't tried them.
1. Unloadc all 'clusters' before starting the procedure. They
are deleted in step 5, above. If you 'unloadc' them first you
can probably skip step 5, a small tree of links will be left
behind. [ I did it the way I described, I'm sure this
variation would work, but I haven't done it]
Hope this helps.
