View source for Rocks: Adding a roll to an installed system

== Rocks 5.4 ==
* Ref: http://www.rocksclusters.org/roll-documentation/service-pack/5.4.2/
* Source: wget http://www.rocksclusters.org/ftp-site/pub/rocks/rocks-5.4/linux/service-pack-5.4.2-1.x86_64.disk1.iso

* As root, make sure to remove any old Service Pack Rolls:
<pre>
# rocks remove roll service-pack
</pre>

* Apply the new Service Pack Roll:
<pre>
# rocks set host attr localhost roll_install_on_the_fly true shadow=yes
# rocks add roll service-pack*iso
# rocks enable roll service-pack
# cd /export/rocks/install
# rocks create distro
# rocks run roll service-pack | bash
# init 6
</pre>

'''Note:'''

* The following steps is critical:
<pre>
# rocks set host attr localhost roll_install_on_the_fly true shadow=yes
</pre>

<pre>
This allows the roll to differentiate some post processing as to whether or
not the roll has been added at frontend build or after installation.    
The processing steps are critically different in these cases
