Last night I decided that I'd try and turn my friend's PC into a
diskless X terminal using OpenBSD.
The first step was to create a root filesystem. To do this I figured
I'd create a root directory for it and use nullfs to mirror the OpenBSD
server's usr, bin, sbin and other sharable directories.
The next step was to create an etc, I did this by creating a union
mount in there where the server's etc was the 'underneath' layer.
This all worked OK until I exported it via NFS and then (to test it) I
mounted it for testing on the server. The 'underneath' layer of the
etc directory was not there, neither were the nullfs mirrored
directories
... eeek !!!
I guess that this is reasonable having read up on how 4.4 BSD serves
NFS - but it doesn't feel right semantically, whats everyone elses take
on this ?
Shouldn't the NFS server export directories (execepting permissions) as
they appear on the local machine ?
Cheers,
Rupert.
