-# The rpm installation heavily bases on the y2pmdxs script from Lars Mueller
-# <lars@m5r.de>.
-
-#
-# We assume (one) two nfs shares exported:
-# 1) the diskless linux root filesystem
-# 2) /tmp/dxs as a special rw exported share for temporary files
-# 3) the client does have only one ethernet interface ---> eth0
-#    this is passed via the mkinitrd
