My main use of 32-bit libraries is commercial software that is available for
32bit systems only. Yes, that's bad, but I can't do anything about that ATM. I'd
really hate to run (and maintain!) an additional chroot on each of those servers
just to run a single application. I do have i386 schroots on other systems, but
I prefer not to maintain that on each and every server. It might actually be a
bit of problem, because one of those commercial products is our backup
software...

Best,
Michael
