+What it appears you'll need to do initially is build out a chroot
+directory. For example, for a Scientific Linux 6.x install, you'd do:
+    # wwmkchroot sl-6 /var/chroots/sl-6     (or whatever path you want
+to store them at -- run wwmkchroot -h for the help)
+  That will give the base chroot for the VNFS at /var/chroots/sl-6.
+You'll then set the environment variable CHROOTDIR when you execute
+wwinit.
+    # CHROOTDIR=/var/chroots/sl-6 wwinit VNFS
+  I know when you use the 'icr' wwinit functions, it creates a base
+chroot based upon the host OS. But none of the other wwinit scripts,
+by default, create one; So you will need to build the chroot and
+specify where the directory is. Then when the VNFS part of wwinit is
+ran, it will build the VNFS and import it into the datastore at that
+time, setting the one specified as the default VNFS in the
+configuration.
+</code>
 So we start by making the chroot directories, first we'll build a generic centos-6. Then we initialize the warewulf environment.

+Second interface: create a template inside of the chroot environment.
+<code>
+wwsh node set b49 --netdev=eth1 \
+--hwaddr=00:00:00:00:00:00 --ipaddr=10.10.1.55 \

+[root@]# wwsh provision set n[00-15] --fileadd=ifcfg-eth1.ww

+Now, lets put it all together which can form the basis for a script.
+<code>
+# make sure it boots across network, alter BIOS settings
+wwsh node new b6 --netdev=eth0 \
