freebsd stable - Mar 2009 - setting quotas from inside a jail

Hello all,

The subject describes my goal.  I'm aware of the usual caveats - if 
there's more than one jail, no UID overlap, this will really only work in 
one jail if all jails are on the same filesystem, etc.

I found a very, very old post that has an... interesting... technique:

http://groups.google.com/group/mpc.lists.freebsd.hackers/msg/2b92fc66ac72efa6?hl=en

It actually works.  "It" being I suppose the fstab trickery in the
jail.
I need to test this some more, but it does seem possible to edit quotas 
inside the jail, which is my basic goal.  I don't want my provisioning box 
to have to hit the host just to alter quotas in one jail that needs them.

Just looking for any warnings/caveats about the above and what might be 
different 6+ years later...

Thanks,

Charles

That's my post.  Yes, we still do this.  It still works.  Over time,
sometimes things get out of sync.  If that happens, go to S, shut
off quotas, do a quotacheck, turn them back on.
