Because too many people no longer seemed to understand the
implications of chroot this has already been done in CVS.
The rsyncd.conf.5 manpage specifically mentions this under the
"use chroot" directive.
it has the disadvantages of ... implying the
--numeric-ids option because /etc/passwd becomes
inaccessible.
It is also specified in rsync.1 under --owner
On most systems, only the super-user can set file
ownership. Note that if the remote system is a
daemon using chroot, the --numeric-ids option is
implied because the remote system cannot get access
to the usernames from /etc/passwd.
And again under --numeric-ids
The bases are pretty well covered. Thanks for the thought.
It just hasn't yet made it into a released version. Once it
is it will take a few months to get into the packaged
distributions.
