Does anyone know how to use Yum to create a jailroot/chroot environment? I tried: [root@linuxjohn4 fc3]# yum --installroot=/usr/jailroot/fc3/ install gcc Repository updates-released already added, not adding again Repository base already added, not adding again Setting up Install Process Setting up Repo: base http://linuxjohn.intel.com/pub/fedora/linux/core/Null/i386/os/repodata/r epomd.xml: [Errno 4] IOError: HTTP Error 404: Not Found Trying other mirror. Cannot open/read repomd.xml file for repository: base failure: repodata/repomd.xml from base: [Errno 256] No more mirrors to try. Has anyone done this? Basically I would like to create a jailroot of Fedora Core 3. It seems like using Yum to create a jailroot would be a natural extension of its capabilities but I am not quite sure how to do it. Thanks, John
