hi,

I'm seeing problems when saving files via NFS on a RS6000.
Our linux machine is exporting its / filesystem to a RS6000
with the following entries in /etc/exports:
/ atmagl50(ro,no_root_squash)

the RS6000 acts as a NFS-client, and mounts the root-filesystem
of the linux machine on a subdirectory (/ns1). then, we'd save this
NFS-subdirectory using tar:

rs6000: tar -cv -1 /ns1

when proceeding, we get error messages for all symbolic-links,
like this:

a /ns1/lib/libtermcap.so.2.0.5 23 blocks
tar: /ns1/lib/libm.so.5: symbolic link too long

etc....

strangely, the machine also cannot archive /dev/zero:
tar: /ns1/home/ftp/dev/zero could not be archived

'ls' shows that the symlinks appear on the rs6000 just the
same way as they do on the linux-machine:

from rs6000:

[atmagl50]/ns1/home/ftp/bin >ls -la
total 420
d--x--x--x 2 root system 1024 May 24 15:05 .

[...]

from linux:

ns1:~# cd /home/ftp/bin/
ns1:/home/ftp/bin# ls -la

---x--x--x 1 root root 77649 Feb 26 1996 tar
lrwxrwxrwx 1 root root 4 May 24 16:05 zcat -> gzip

could there be a problem with the NFS-implementation on Linux ?
I've check that Linux-Linux works fine (yes, does...).

OSversions:
linux = 2.0.21
rs6000 = aix3.2.50

any help appreciated.
