I'd feel more pressed to help find a satisfying solution if I were
convinced there was really problem. What specific root owned file needs
are you running into?

I'm not saying you're wrong, but you haven't presented a compelling use
case. Convince me.

AFS isn't a Swiss Army hammer, and this may be an application that it's
not particularly well suited for. It's quite a bit different from local
file systems, and it may not meet all the needs of your chrooted
environment. Or perhaps it just doesn't meet some common conventions that
aren't really requirements. Either way, it seems an interesting problem t=
me. I'd like to know more about the issues you're trying to deal with.
