Cool. So if there was a RPM package which contained a barebones Fedora image and some management scripts, I don't imagine it would be too difficult to do things like build RPMs inside that with e.g. different SELinux policies to the host. Any supporting RPMS required inside the guest could be installed via a script either from host media or over the net, then the final RPM (or whatever is being created) could be copied back out to the host before discarding the guest instance. It would not be as fast or simple as chroot, but I suspect it would work pretty well, especially if the guest dispenses with all non-essential startup. - James -- James Morris <jmorris@xxxxxxxxx> -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
