Apologies for the long turn-around on this, but I've been off in bug-squashing mode...

No, I haven't tried the included nfs root support (you mean the install-over-nfs feature?). But as you say, it shouldn't have much bearing on an NFS mount being read-write or read-only in my case.

The only messages on the server, in /var/log/messages, are of the form:

rpc.mountd: authenticated mount request from mynode:881 for /remote/dir/foo (/remote/dir)

I don't see any errors or warnings indicating a problem, and there's no warning on the client side that the mount is being done read-only. It just is, and I get EROFS if I try to create, modify or delete a file on the mounted filesystem.

It's tangential to this, but have you tried the included nfs root
support?

mount /proc and /sys
mount the root filesystem read-only over NFS
unmount /proc and /sys
pivot_root to the NFS root
mount /proc and /sys again
mount more filesystems read-write

The NFS server is an ELAS3u6 system, and it's exporting the directories read-write. I can drop to a shell (bash) from the linuxrc script and issue the mount by hand, and I get the same results: it succeeds, but is read-only.

Any messages on the server?

Bill
