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
searching: http://www.sysimage.com
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.
