Hi,

I'm trying to get Linux running on a PPC board to mount an NFS root
filesystem off of a Windows XP machine -- in this case the NFS filesystem is
exported by the NFS server in Cygwin.  While it mounts OK, Linux fails to
come up due to various errors, e.g.

mount: only root can do that
awk: cmd. line:2: fatal: cannot open file `/proc/mounts' for reading (No
such fi le or directory)
                Welcome to Wind River Linux

If I chmod 777 the entire root filesystem from within Cygwin, it gets
further (to the prompt) but then it won't let me login with root.  I know it
probably has to do with the fact that all the files in the root filesystem
have my windows login name as the user instead of root. 

Has anybody successfully booted Linux off of a cygwin NFS exported root
filesystem?

Thanks!
