Built an IUK (between two builds of feature/buster FWIW) twice on my sid system with squashfs-tools 1:4.3-7.0tails1 and… they differ :/ Attaching the diffoscope HTML output.

While doing the exact same test with 1:4.3-3.0tails4 produces identical IUKs. So unfortunately, it might be that I was remembering things right and we may need at least one of the patches squashfskit has, that got dropped between 4.3-3.0tails4 and 4.3-7.0tails1. My next step would be to prepare 4.3-8.0tails1 with all squashfskit’s patches applied, and redo this test. What do you think? Wanna prepare this package?

Test procedure:

export IUK_CHECKOUT=/home/intrigeri/tails/iuk/git/
export PERL5LIB_CHECKOUT=/home/intrigeri/tails/perl5lib/git/
export SOURCE_DATE_EPOCH=1536063343
export ARTIFACTS=/home/intrigeri/iso/tails/dev/
for i in 1 2 ; do
    sudo su -c "cd ${IUK_CHECKOUT:?} && \
          SOURCE_DATE_EPOCH=$SOURCE_DATE_EPOCH \
          LC_ALL=C \
          PERL5LIB=\"${PERL5LIB_CHECKOUT:?}/lib\" \
            ./bin/tails-create-iuk \
               --squashfs-diff-name \"test.squashfs\"           \
               --old-iso ${ARTIFACTS:?}/tails-amd64-feature_buster-3.12-20190105T1511Z-b8a9438cbb.iso \
               --new-iso ${ARTIFACTS:?}/tails-amd64-feature_buster-3.12-20190107T1235Z-c2b3251454.iso \
               --outfile \"${ARTIFACTS:?}/$i.iuk\""
done && cmp ${ARTIFACTS:?}/{1,2}.iuk
