Comment 21 for bug 485709

I don't use LTSP but I've found two major problems using nfsroots on Lucid, and probably Karmic as well:

1. By default NFS wants locking, which creates a circular dependency: rootfs -> statd -> portmap -> local-filesystems event -> rootfs -> statd -> etc.

2. To work around that problem, you can put "nolock" in /etc/fstab for the rootfs. However this runs into a bug in mountall where it doesn't notice the rootfs has been successfully mounted, so it will loop forever trying to finish mounting the local filesystems.

These two problems are described in more detail in bug #537133 with a patch that fixes the second issue.
