Hi $LIST, I would like to reduce the squashfs image size for a particular setup. Both to reduce transfer time when netbooting, and to reduce the amount of RAM used.
I would like to run rm -rf squashfs-root/usr/share/doc/* squashfs-root/usr/share/locale/* squashfs-root/usr/share/man/* (the files in these directories are not relevant for my use case because there is only one single application running in full-screen mode, and no shell access for the user) before the squashfs is created. Where would I have to add that? Also, I would like to run mksquashfs with additional parameters -b 1048576 -comp xz as that seems to shrink the image even further, thus reducing transfer times (even though RAM usage will probably be the same). Where would I specify that? I searched https://debian-live.alioth.debian.org/live-manual/stable/manual/html/live-manual.en.html man lb_build man lb_config for "squashfs", but none of the hits seems relevant to my case. So far, I'm using unsquashfs once live-build is done, and run the commands manually (that's how I know I'm shaving about 60 Megabytes off of the image with my changes), but I would prefer it if mksquashfs wouldn't have to run twice. Kind Regards, Stefan Baur
