Looking good! Also mmm, a kernel that's 800k in size :-)
Are these changes commitable?
I didn't change any code, just modified the superblock
a little bit. In particular, it now says it is 8k in size
and some bits that were undefined (all 1's) but are
interpreted by our kernel, are now set.
Ah, I see. You adjusted the filesystem to fit the kernel rather than the
other way round.
Shouldn't be difficult to make the kernel accept the
original superblock.
This is a potentially live filesystem type, not a historical archive.
There appears to have been a resurgence in running RISCiX both under
emulation and on real hardware.
N.B. fsck and other userland tools are still confused
by the "alternate superblocks". I guess these also need
to be more relaxed about undefined bits.
Let me know if there's anything I can do to help.
