The client is diskless. The problems I'm reporting are with it's /home mount. It's root filessystem is also a nfs mount (but that is exported form a _different_ nfs server). I modify the nfsroot using chroot on the server. I *think* this might be because of /proc mounted in the chroot get exported to the client? Any insight? I've been trying all sorts of combinations yesterday (/proc mounted and not mounted in the chroot) and I haven't been able to reproduce the error. Strange becuase it definitely happened when was shutting down the nfs_home_server while everything else was up and running. Perahps it is also worth noting that I'm booting the client with live-initramfs. /home gets mounted after the real filesystem(aufs,nfs+ram) comes up. Once the client has booted I can use /home. But it doesn't show up using 'df', and it is not present in /etc/mtab However it does show up in /proc/mounts nfs_home_server:/home /home nfs rw,vers=3,rsize=32768,wsize=23768,hard,nointr,proto=tcp,timeo=600,retrans=2,sec=sys,addr=192.168.2.2 0 0 Sorry for the convulated reply.
