Investigate why the reproducible ISO is larger than 3.0~beta2
Originally created by @intrigeri on #12347 (Redmine)
3.0~beta2 was 1099M, my current builds from
feature/5630-deterministic-builds
are 1191M. I’ve verified that the
package list is almost the same. The size difference comes from
live/filesystem.squashfs
only. The “funny” thing is that in theory, we
include less data in this ISO: we exclude/delete lots of stuff that
would harm build reproducibility.
So, either we somehow include more data in the SquashFS, or the newer
mksquashfs
compresses less well than the one we used before.
