Re: [PLUG] utility to image a linux host?

with dd it's theoretically very easy:

dd if=/dev/sda of=/mnt/somewhere

the filesystem mounted on /mnt/somewhere needs to have enough free space 
to hold the entire contents of /dev/sda.  This won't help you create and 
iso of course.

It's funny that you asked about an iso because I came across this in my 

sysimage is a little more complex that I'd like: ie client-server and 
focused around building an image server that can be used to create many 
clients.  It is flarcreate and jumpstart all wrapped up in a custom 
package..  It does seem to allow bare metal restores to a "golden image" 
though which is very handy.
