It depends on if you're doing something that's one shot or
not. It's
not hard to do dropping into a shell, but it's going to leave you with a
live CD that you have to manually reproduce everytime. Using an actual
post script will be able to be reproduced at will (and changed, etc)
over time
For my needs it sounds like dropping in to a shell would be OK -
anyone able to explain how to do this?
From the sounds of it though a post script would be better for most
circumstances including mine...I don't know enough to be able to help
with organising how this would work but that's just my two cents.
Thanks to people for their thoughts :D
