Amen.
I managed to upgrade without problems by just
following the notes -- this is simply great!
In addition to the notes, I diff-ed /n/myfs/adm/timezone with
/n/dist/adm/timezone, and noticed that CET had been updated
(probably I skipped an update).
Next time I probably would also mv adm/timezone to 3e_adm/timezone.

Same here. The trick seems to be the number of arguments given to 9fs:
9fs super
(the fs is named super) does not allow me to create files, but
9fs super /n/super
does.
Still have to finish reinstalling local applications
and clean out the /3e_* stuff, get the remote printer
access working again...
(and have again serial mouse support, to be able to
use the cpu/auth server also as terminal -- without
mouse rio is nicely view-only, until the screensaver
kicks in... :-)
I have not yet installed 4e drawterm; 3e drawterm exits
with 'bad message type in devmnt' when I try to connect
it to 4e cpu/auth -- I assume this is to be expected
(or should 3e drawterm still work?)
I made a crude attempt at folding my attach message
'-l user' aname hack back into 4e u9fs; it seems to work;
I attach the diffs below; 'review' comments are welcome.
Axel.
