Well, I've backed out the eaccess() use in /bin/test for now. I agree with you that ultimately this model will fail, but the longer we can delay it the easier my life will be trying to manage the cluster and get packages built. I haven't yet tested the stability of 5.0 clients in the bento cluster; hopefully it won't be too bad, but any stability problems cause interruptions and increased work for me. For example, for some reason the gohan machines won't reboot on their own in response to a reboot command, and have to be power cycled (they mostly come back up okay if they panic, but sometimes they get stuck and need power cycling still). This means I can't currently automate booting them into a 5.0 nfs snapshot when I want to build 5.0 packages. Kris
