Looking back through the archives, I noticed a few pr's by John Kohl
describing and suggesting fixes for various unionfs problems,
including kern/792 & kern/892.
Have these been fixed? I suspect a lot of my recent wedges have been
due to me mounting stuff like:
fdesc /dev fdesc rw,union 0 0
/dev/sd0f /z/0 ufs rw 1 2
/z/0/src /usr/src null rw 0 0
/var/obj /usr/src union rw 0 0
fdesc on /dev type fdesc (local, union)
/dev/sd0f on /z/0 type ufs (local)
/z/0/src on /usr/src type null (local)
<above>:/var/obj on /usr/src type union (local)
If there are any known problems will nullfs mixed with union I'll give
the nullfs the flick and union mount /var/obj over /z/0/src. That is,
of course, if union is relatively stable.
This is with a kernel with sources from 950517.
PS: since mycroft's changes to dev/isa/com.c of 950513, 'break' on the
comconsole works! Before then I could use ddb from the comconsole, but
it would flat out ignore my ~# from tip... This is an excellent fix :)
