Here's my take (I use CVS for lots of other things than FreeBSD
src/ports/etc as well).
- ~/.cvsrc:
[21:27:04] mortis:~
(ttyp4):{162}% cat .cvsrc
diff -u
update -d -P
checkout -P
So I can't forget flags ;>
- When changing branches, just whack your src tree and cvs co clean.
It's not THAT slow (cvs co of ports takes ~10 minutes, src may be closer
to a half hour.) We have machines running HEAD (-current), RELENG_3, and
RELENG_2_2, so I'm constantly whack/co'ing back and forth (hint: newfs is
much faster than rm -rf ;)
- So with a clean /usr/src, set your CVSROOT to wherever your CVS repo is
(/home/ncvs seems to be the preference, I use /usr/cvs (also a seperate
partition) )
Then something along the lines of (cd /usr && cvs co src)
And run it under time(1) while you're at it, so you can put how long it
took on your webpage! :)
As far as the actual updating, I think the 'right' way is something like:
* Update to latest RELENG_2_2 (build/installworld)
* Update to 3.1-RELEASE (make update I think is preferred)
* Update to latest RELENG_3
At least, that's the way I'd do it if I had to now. Slower, lots of
steps, but at least they're small ones.
