I've assembled some notes from old manuals and other sources
on the formats used for on-disk file systems through the

directly to me, rather than to the whole list.)
I am trying to bring up a Sprite cluster. 
I was able to get the demo system running on a SPARCstation 1+ by dd-ing
the boot image to a disk. Now I wane label an additional disk, make LFS,
... make the new disk bootable to get more free disk space then I have
on the premade boot image. But I can't get a label on the disk with
labeldisk nor did I succeed using fsmakeprompt. The later crashes...
Next step is to bring a SPARCstation 2, an IPX and two ELCs into the
Is there someone out there with Sprite experience who can help me?
Additionaly I was not able to get the PMAX image to work on my
DECstation 5000/240 nor my DECstation 3100. Any ideas? Do I really need
a DECstation 5000/200 for this?
A mixed architecture, distributed single system image OS capable of
process migration that presented the cluster to a user as a single,
large multiprocessor machine. Pmake and LFS (Log-Structured File System)
originate from Sprite.

ksh93 is a different animal, from a different group, and problems
there are not surprising (sadly).
On the flip side, they do take bug reports seriously.

I don't know. It's worth double checking the current license; it
changed sometime in the past year or two.
The Plan 9 troff is certainly a descendant of the ditroff you
found, for whatever that's worth.
