The issue can be reproduced by comparing two different official images from https://nixos.org/nixos/download.html, e.g. x86_64 and i686. https://d3g5gsiof5omrk.cloudfront.net/nixos/17.09/nixos-17.09.3047.8bce347f02f/nixos-minimal-17.09.3047.8bce347f02f-x86_64-linux.iso https://d3g5gsiof5omrk.cloudfront.net/nixos/17.09/nixos-17.09.3047.8bce347f02f/nixos-minimal-17.09.3047.8bce347f02f-i686-linux.iso
It takes over 1h to compare those 337M ISOs. I guess that minimal case would be non-writeable file in non-writeable directory in squashfs in ISO image. Neither tar nor squashfs alone triggered the issue (i.e. without ISO image). _______________________________________________ Reproducible-builds mailing list Reproducible-builds@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/reproducible-builds
