Hi, I would like to remaster a Debian based live CD (grml - www.grml.org, in this case) by copying the system from the squashfs image, chrooting to it, making the necessary modifications and squashing the resulting system back up. It works nicely enough, BUT: All manners of cache files, .deb files and such are left lying around and increase the size of the final ISO quite dramatically. So, the question is this: How do I prevent those files from making it into the squashfs? This far, I have deleted the contents of /var/cache/apt /var/lib/apt and /var/lib/dpkg. That, of course, renders apt and dpkg unusable, but that's mostly OK. I thought about bind-mounting directories external to the directory structure to those directories so the changes I make would be preserved but not written to the CD. Would that be a good idea? And what other files and directories can I leave out of the squashfs to make the whole thing a bit smaller?
Any input will be much appreciated. Thanks, --j
