+Next build a hybrid VNFS, this is the way to add packages to the nodes.  For example NTP.
+<code>
+cd /var/chroots/centos-6/
+mkdir vnfs
+vi etc/fstab (inside of chroot area, edit)
+.168.1.217:/var/chroots/centos-6 /vnfs nfs defaults 0 0
+wwvnfs --chroot /var/chroots/centos-6 --hybridpath=/vnfs
+Overwrite original: y
+# reboot node, observe mount, then add NTP to chgroot
+yum --tolerant --installroot /var/chroots/centos-6 -y install ntp
+vi etc/init.d/ntpd (inside of chroot, edit)
+# chkconfig: 35 58 74
+# then make the following links in etc/rc[3|5].d/S58ntpd pointing to ../init.d/ntpd
+vi etc/ntp.conf (inside of chroot, sole contents are, IP is master on private network)
+restrict default ignore
+restrict 127.0.0.0
+server 192.168.1.217
+restrict 192.168.1.217 nomodify
+wwvnfs --chroot /var/chroots/centos-6 --hybridpath=/vnfs -y
+VNFS 'centos-6 has been imported
+# reboot node
+</code>
+Then build the node up:
+  * use yum to install the openlava 2.2.1 RPM (pulls in tcl)
+    * copy the openlava config files into the centos-6 are
+  * use yum to install postfix
+    * add links in rc3.d and rc5.d
+    * remove sendmail links
+  * yum install perl
+  * yum install munge
+    * build RPMs from tar ball
+  * rebuild the VNFS and reboot
+Sometimes you can edit the files in the chroot directly, sometimes you must modify the installtoot directly.  It's easiest to just do the latter all the time.
+<code>
+[root@petaltail ~]# cd /var/chroots
+[root@petaltail chroots]# chroot centos-6
+[root@petaltail /]# pwd
+/                          <--- inside of installroot
+[root@petaltail /]# mkdir /var/log/munge
+[root@petaltail /]# chown munge:munge /var/log/munge
+[root@petaltail /]# mkdir /var/log/slurm
+[root@petaltail /]# chown slurm:munge /var/log/slurm
+chown: invalid user: `slurm:munge'
+# since the passwd|shadow|group files come from database you need to create the relevant lines
+[root@petaltail /]# chown slurm:munge /var/log/slurm
+[root@petaltail /]# exit
+exit
+[root@petaltail chroots]# ls
+centos-6
+# outside edit commenting out rc.local directives making these dirs etc
+[root@petaltail chroots]# vi centos-6/etc/rc.local
+# and don't forget
+[root@petaltail chroots]# wwvnfs --chroot /var/chroots/centos-6 --hybridpath=/vnfs  -y
+# reboot node
