| |
Having played a bit with a diskless setup (using an eprom and the NFSroot option) I have discovered that the main obstacle to a really useful diskless CPU server is the inability to swap over nfs. Is anybody working on this? How hard would it be?
The only other obstacles I can see to creating a setup where multiple sytems share the same root filesystem is a modified version of mount that doesn't use /etc/mtab but uses /proc/mounts, and could understand some fancy substitutions in the fstab, eg
server:/usr/export/var.@HOSTNAME@ /var nfs defaults 0 0 server:/usr/export/swapfiles/swap.@HOSTNAME@ none swap defaults 0 0
would mount the appropriate things off the server without having a different fstab for different clients. This however I can do myself. (I don't believe it is possible to share /var, though I may be wrong. /var/log/wtmp at least must persist over reboots (so it can't be on a memfs, unlike stuff in /var/run and /var/lock) and must be unique to each machine).
Also, a memfs for /tmp on diskless machines would be nice - there is one around, I believe. Does anybody know where it hides out and how stable it is?
