That is the problem. There isn't really a package associated with nfs diskless clients. It isn't a "thing" as a "configuration". And so I don't know if there is a single canonical owner for it. It would need some discussion to determine the best place for this. Perhaps others will have more insight into this topic. The topic comes up for discussion periodically. Usually we tinker with things until we scratch our particular itch and then the topic is forgotten until the next time it comes up. There are so very few people using nfs diskless. > > File /etc/rc.local: > > mount -a -t nfs > > Thanks; I can never remember where the "do this after startup" stuff > goes. I did this and it worked. And if you switch over to the "auto" and "manual" settings then this isn't needed anymore. :-) > I tried Michael's suggestion to use _netdev, before changing rc.local, > but it didn't help.

What that actually does is in the /e/n/if-up.d/mountnfs script it mounts nfs types first and then mounts _netdev types second. So that it can apply the layers in the right specially specified order. But since the problem was that /e/n/if-up.d/mountnfs isn't called unless the interface is brought up then it isn't called to mount _netdev devices either. > On the one hand, network access is always available in a diskless > setup; on the other hand, the regular startup sequence never gets an > indication that the network has come up, which I guess means neither > _netdev not nfs mounts fire.

I am not familiar with MythTV at all and so can only speculate from the reported behavior that it must be wanting something down that directory path. :-) > Thanks also to Roger for his suggestions about tempfs; I'm going to look > into them.

By default the /etc/fstab will be empty. So instead of starting with a running system and trying to push it into an nfs client I started with a very small empty system and grew it into what I needed. So for you I recommend removing all of the core system mount points (including the tmpfs items that Roger recommended) and starting off empty too. However if you want /media/* mount points then of course you would want those to be available. But probably not: > none /media tmpfs defaults 0 0 But rather something like the new default entries like these. This is from my systems: proc /proc proc defaults 0 0 /dev/cdrom /media/cdrom0 udf,iso9660 user,noauto 0 0 And I also have /tmp, /var/tmp, /var/log, and /media, on tmpfs partitions for the nfs diskless clients. And by not showing my entries for those I avoid needing to list their correction mount options. I will leave that for Roger. :-) Bob
