+# 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
