Re: [ezjail] ezjail-admin install from alternate src/obj?

That works, but as it is we already have an nfs-exported src/obj for each
arch. So that's already covered.
Try two source trees (one for the host, one for the jails).
Right before make world, you could try moving away your old src and obj
cd /usr && mv src src.amd64 && mv obj obj.amd64
then moving your 32 bit into place
mv src.i386 src && mkdir obj
cd src && make TARGET=i386 buildworld
That's essentially what I'm doing now (minus the build, I just have ezjail
do the installworld) - I unmount the 64-bit usr and obj and mount the
What I'm hoping for is some way of mangling ezjail into selecting which
src+obj tree to install from. For example, on 64-bit hosts, I have this
[root@h21 /home/spork]# mount -t nfs
192.168.1.111:/home/usrsrc-8-64 on /usr/src (nfs)
192.168.1.111:/home/usrobj-8-64 on /usr/obj (nfs)
192.168.1.111:/home/ports-8-64 on /usr/ports (nfs)
192.168.1.111:/home/usrsrc-8-32 on /usr/src-32 (nfs)
192.168.1.111:/home/usrobj-8-32 on /usr/obj-32 (nfs)
Any ideas? I probably need to become more familiar with the whole build
system to figure out how best to do this. I'm fairly certain that if I
tried to manually do an installworld out of "/usr/src-32" it would likely
blow up or install from "/usr/obj".
When you are done with the jails, mv your src and obj trees out of the
way if you need to update the host.

There seems to now be official support for running 32 bit jails on a

our case it's to allow jail portability between i386 and amd64 boxes).
What I've been doing so far is simply nfs mounting 32 bit /usr/src and
/usr/obj on the host when updating the basejail.
I did experiment at some point with pointing to an alternate src tree,
but as I recall that didn't really work out very well due to the right
/usr/obj not being found (this was an installworld-only install, ie:
Any ideas on how to support mixed arches with ezjail going forward?
