I want to install the Hot Patche 5 on my Linux OES Suse 9 server. I have
Zenworks 7 SP1 Imaging component installed on it.

I've found that I will probably need to backup some important files that I
have previously modified. For exemple, I have modified the
/srv/tftp/boot/initrd file to allow a customized zen menu and I have also
modified the pxemenu.txt to have a customized Pxe menu. So, these 2 files
will have to be backup.

Is there other things I need to know before making this upgrade? or some
good advices before proceeding?
