Description of problem:
On logging in over the network using ssh with X11 forwarding, ld.so reports an error on missing shared library for executing xauth:
/sbin/xauth: error while loading shared libraries: libXau.so.6: cannot open shar
ed object file: No such file or directory

Version-Release number of selected component (if applicable):
anaconda-11.5.0.59-1.fc11.kh.1.s390x

How reproducible:
Boot/IPL Fedora on s390x install system from kernel.img, generic.prm, and initrd.img, configure network (linuxrc.s390) and then login over the network using ssh with X11 forwarding.

Actual results:
Xauth cannot be executed and hence no MIT magic cookies for X11 authentication can be configured by sshd.

Expected results:
Even though I would not recommend using X11 for GUI install, since it requires recent X extensions many X servers might not have, but rather VNC instead, xauth should still be executable without error.

Additional info:
I had to copy the following shared libraries into initrd.img to make it work:
-bash-4.0# cp -va /usr/lib64/libXau.so.6* initrd/lib64/
`/usr/lib64/libXau.so.6' -> `initrd/lib64/libXau.so.6'
`/usr/lib64/libXau.so.6.0.0' -> `initrd/lib64/libXau.so.6.0.0'
-bash-4.0# cp -va /usr/lib64/libXext.so.6* initrd/lib64/
`/usr/lib64/libXext.so.6' -> `initrd/lib64/libXext.so.6'
`/usr/lib64/libXext.so.6.4.0' -> `initrd/lib64/libXext.so.6.4.0'
-bash-4.0# cp -va /usr/lib64/libXmuu.so.1* initrd/lib64/
`/usr/lib64/libXmuu.so.1' -> `initrd/lib64/libXmuu.so.1'
`/usr/lib64/libXmuu.so.1.0.0' -> `initrd/lib64/libXmuu.so.1.0.0'
-bash-4.0# cp -va /usr/lib64/libX11.so.6* initrd/lib64/
`/usr/lib64/libX11.so.6' -> `initrd/lib64/libX11.so.6'
`/usr/lib64/libX11.so.6.2.0' -> `initrd/lib64/libX11.so.6.2.0'
-bash-4.0# cp -vau /usr/lib64/libxcb.so.1* initrd/lib64/
`/usr/lib64/libxcb.so.1' -> `initrd/lib64/libxcb.so.1'
`/usr/lib64/libxcb.so.1.1.0' -> `initrd/lib64/libxcb.so.1.1.0'

Sorry, I don't have access to a working build system (pungi) so I cannot modify and test the build scripts to account for the necessary changes.

This is what xauth is linked against:
