[20:35] <cdriscoll> hello - i've been making a custom ubuntu 22.04 desktop iso with preinstalled packages and some configuration changes for a couple years now via unsquashing filesystem.squashfs from the ISO, then chroot to the extracted dir, make my changes, and then resquash the filesystem and recompile the ISO.  This seems completely different with 24.04 in terms of the squashed filesystems in the ISO.  Is there 
[20:35] <cdriscoll> any documentation that I'm missing or a cool way to accomplish something similar?
