You have several problems. First, the NFS server is set up to export

	/nfs4exports
	/nfs4exports/data
	/nfs4exports/home

It is NOT exporting /mnt/nasdata. You can try "showmount -e" on the
NFS server to see what it's actually exporting. I think you'll find the
things being exported all start with /nfs4exports. If that's the case,
try:

	mount 192.168.1.48:/nfs4exports /mnt/box48

See my other comments below.

Looking at your bindmounts, the actual mountpoints that you're using
aren't absolute. I think you want:

	/home/data    /nfs4exports/data    none    rw,bind    0 0
	/home/home    /nfs4exports/home    none    rw,bind    0 0

And ensure that the "/nfs4exports", "/nfs4exports/data" and
"/nfs4exports/home" directories all exist BEFORE you execute the
bindmount.
