Hi Paolo,
I've just done this myself; it turned out to be surprisingly easy in the
end. The FreeBSD slices on my disk are laid out like this:
ad0s1a = / for STABLE install
ad0s1b = swap, shared by both installs
ad0s1e = /var for STABLE install
ad0s1f = /usr for STABLE install
ad0s1g = /tmp & /var/tmp (symlinked together), shared by both installs
ad0s2a = / for CURRENT install
ad0s2e = /var for CURRENT install
ad0s2f = /usr for CURRENT install
ad0s2g = /local/0, shared by both installs
If I was to add a second disk to this box, it would be mounted on /local/1.
/usr/{src,obj,local,ports,X11R6} and /home are symlinked to appropriate
directories on the large /local/0 partition -- separate /usr/src and
/usr/obj for each install, of course. This partitioning scheme was
suggested by Nik Clayton; it keeps everything whose size is pretty much
fixed in small dedicated partitions, and everything that will grow over the
life of the system on the same big partition -- less chance that you'll run
out of space on (say) /home and have to start sylinking things into
/usr/local, or whatever.
I did the initial install from a 4.4 CD -- set up all the slices and
partitions as above, but didn't set mountpoints for the CURRENT-only
partitions. Then just to see if it wll worked, did a second 4.4 install on
the CURRENT partitions, with the shared stuff mounted appropriately. With
BootEasy as the boot manager, I can select which install to use simply by
hitting F1 or F2 at boot time. Sysinstall and booteasy all appear to be
perfectly happy with this arrangement; the two installs don't interfere
with each other at all, as far as I can see.
I've upgraded one install to -STABLE and will get the other one up to
-CURRENT over the weekend, hopefully. I chose to do this with a local
mirror of the CVS repository in /home/ncvs, from which I can checkout and
build whatever versions I want... you could also just run two cvsup jobs to
update your respective -CURRENT and -STABLE /usr/src directories. It
probably doesn't make much difference which method you use, unless you're
making extensive local changes that you want to check in to a local
repository.
Hope that all makes sense; let me know if you need any more details.
Cheers,
Scott
