I _suspect_ that the changing of the quota roots above is causing a second pass through
a loop somewhere. The code is pretty, um, loopy.
You say a second quota -f run fixes it. I suspect that doing a second quota -f run
is the correct response. Yes there's a bug in there somewhere, but there's a pretty
good workaround available :)
Bron ( but put in a bugzilla entry if there isn't one already, and we'll notice it
again one day )
