Yes I did indeed. :-C

This is the Result of two Boners of mine. :-C

I had copied various Stuff from the old /export/root Setups to save Time,
among them the fstab's with Lots of Mounts. I edited them to Taste, but
I actually forgot to change the OS Version to be mounted; I.e., the Clients
mounted /export/exec/sun4.sunos.4.1.2 and /export/exec/kvm/sun4c.sunos.4.1.2
instead of ...4.1.3.

Normally, I'ld expect that trying to mount 4.1.2 off a Server which hasn't
got any 4.1.2 installed results in an Error. No it doesn't. Because in
copying /export Stuff over, I accidentally copied the appropriate Links,
too ... which, because the former Server was a 4.1.2 sun4c Machine, pointed
to /usr and /usr/kvm.

Thus, my Clients requested sun4c 4.1.2 and were fed sun4m 4.1.3. X-P

I discovered this when I verified that the Clients did in Fact mount a
sun4c /usr/kvm, which I was told by various Answers. Another Hint was
that ps has to look at the same Kernel the Machine booted from - This
wasn't applicable to me because /vmunix was the only Kernel around.

No Answer to this one yet - I'ld be happy to see such a Thing, though.
