+#-- IBMhpc.postinstall
+#--    Run this script from your <profile>.postinstall to perform the following
+#--    general setup in your diskless image for your HPC cluster:
+#--        - create entries in /etc/fstab for basic filesystems 
+#--        - enables the "cons" entry in /etc/inittab
+#--        - create initial copies of /etc/passwd and other files in the image
+#--        - turn on the "at" service
+#--        - turn on xinetd
+#--        - 
+#--
+#-- it gets these arguments:
+#--
+#-- $1 = install root (chroot directory for profile)
+#-- $2 = OS version
+#-- $3 = architecture
+#-- $4 = profile name
+#-- $5 = work dir (where genimage is located)
+#--
+#--
