Re: NFS-Root on AIX

I did some further tests with the Device-Number-Problem between Linux and
AIX when using AIX as NFS-Server for NFSroot-Boot.

The Devices finally all were created on the AIX.
FYI: 42*256=10752, 42*256+42=10794

AIX, oslevel 4.3.3.0

FYI: system is uid 0 on this box.

AIX seems to export 16-Bit-Device-Numbers and Linux imports only
8-Bit-Device-Numbers. In 2.2.X the Minor-Device-Number exported by AIX is
split in halves and becomes the 8-Bit Minor- _and_ Major-Device-Number.
In 2.4.x linux works correct, but shortens the Device-Numbers to 8-Bit-Values.

Linux S/390 shows that there is no difference in 2.2.16 running on little
oder bigendian machines.

All the tests where done with redhat 7 based system, including the S/390 ;-)
