That may be the case, but at least we had the discussion.
I'm worried only by PJP's assertion that you can't trust the chroot to have the zone file you have yourself.
In that case nothing short of stuffing the zone *into* TZ will help which I'd like to avoid.
Unfortunately all of this complicates the API.
I'll wait and see what PJP comes up with for the tzalloc solution to solve two birds with one stone.
Cheers,
Carlos.
