Yes, I agree, that is the proper way of doing it. Sometimes it's useful for a quick test, though, because it's much quicker than building from scratch.

There will be other use cases that need network access, though, e.g., downloading an SSH key from somewhere else, or synchronising a file with a remote host.

It seems that it's pretty easy to get network access up and running: it just means copying /etc/resolv.conf and /etc/hosts from the host machine to the chroot jail. Ideally what would happen is that the chrooted versions would get saved somewhere (outside the chroot), the host machine's versions would get dropped in, the shell or script would be run, and then the originals would be put back before the rebuild.

How about a '--network' option that adds this in? (Probably best not to do it by default, in case the user is trying to alter one of those two files, in which case the alterations would fail when the originals get put back.) To my mind, that would make it um heap big more useful.

Ta.
