--- Comment #5 from Jamie Gritton <jamie@FreeBSD.org> ---
While it does make sense to root from the jail's root under exec.clean, it
unfortunately clashes with a decade of current practice.
I'll consider a change, and see what people think, but I can't guarantee it'll
happen given the long history. It seems reasonable that if a user is specified
(even directly like -U root), then it would still chdir to its home, but in the
absence of a user, starting in "/" would in fact be the most expected outcome.
