I started wondering about the possibility of reproducible builds for distro live CDs. Suppose you have a set of packages where every binary is already reproducible — how much work is left to do?
So far the main finding is that mksquashfs with default options produced a file with a different hash sum literally every single time I tried.
I wonder if there's either SquashFS can be produced deterministically or there are alternative compressed read-only filesystems with that property.
