I've been running an nfs-root setup on a gentoo box (served from a gentoo server) and I've run into a few issues along the way - sometimes as a result of kernel upgrades. Honestly, NFS seems like a big bucket of fail to me - the older versions mostly work, but rely on a cobblework of daemons/layers to provide various features and it is completely insecure. NFSv4 might as well be a completely different filesystem and seems fairly complex to get working in a secure fashion (kerberos, etc). I could only imagine what it would be like to get it to work for my root filesystem with PXE boot. Whenever I run into people and talk to them about file servers on linux it seems like they tend to end up just using samba (not even POSIX) or something like sshfs (which is also a bit of a hack, but one which seems far simpler to use). It just seems like this is a huge gaping hole for linux to have. That said, fixing all the issues could have some far-reaching changes, like switching to GUIDs for UIDs. -- Rich
