Hi,

I'm trying to access remote devices locally by mounting/exporting /dev
nodes over NFS. However, looks like the access requests are treated local
based on major minor numbers (e.g. "cat /mnt-dev-over-nfs/kmg" output is
same as "cat /dev/kmsg")

How can I change this behavior? and if it is at all feasible?

Thanks,
Riya

You cannot.   Things in /dev are a bit like symlinks.  They point to the real
thing, but they are not the real think themselves.
The actual devices are always local to the client host.  NFS cannot provide
access to remove devices.  It can only provides the "links" which you can
follow to your local devices.
