Good idea :-)

mkinitrd shouldn't do anything to your cluster.conf. mkinitrd will always use 
the cluster.conf in /etc/cluster/cluster.conf. Please make sure, that the 
version number of the latest cluster.conf is increased and it is deployed to 
all cluster nodes using a "ccs_tool update /etc/cluster/cluster.conf".

If you want to use fence_drac, you need to put all required perl stuff into 
the chroot environment. This can be either done by 
1) adding all perl stuff into the initrd or
2) adding the perl stuff only into the chroot environment during the boot 
process.

to do this, create a file called perl.list with the following content:

-->snip
perl
perl-libwww-perl
perl-XML-Encoding
perl-URI
perl-HTML-Parser
perl-XML-Parser
perl-libxml-perl
perl-Net-Telnet
perl-HTML-Tagset
perl-Crypt-SSLeay
#####
-->snap

and copy it into

1) /etc/comoonics/bootimage/rpms.initrd.d/
and make a new rpm

_or_
2) /etc/comoonics/bootimage-chroot/rpms.initrd.d/
and run "service bootsr start"
