Hi Thomas, Thanks for the quick and insightful reply!

Then you would need to run “guix pull” to get a current Guix (0.15.0 itself didn’t have this bug.) And finally, run: guix system disk-image --file-system-type=iso9660 \ -s i686-linux \ ~/.config/guix/current/share/guile/site/2.2/gnu/system/install.scm (This command works on an x86_64 machine.) The result will be an ISO that’s corrupt. > What do you get from this xorriso inspection run on a damaged ISO ? > (I tested it with the ISO from https://www.gnu.org/software/guix/download/): > > xorriso -indev guixsd-install-0.15.0.i686-linux.iso \ > -find / -sort_lba -exec report_lba -- \ > >/tmp/xorriso_indev_find.txt 2>&1 I get: --8<---------------cut here---------------start------------->8--- GNU xorriso 1.5.0 : RockRidge filesystem manipulator, libburnia project. libisoburn: WARNING : ISO image size 475636s larger than readable size 473456s xorriso : NOTE : Loading ISO image tree from LBA 0 libburn : SORRY : Read start address 475635s larger than number of readable blocks 473456 xorriso : UPDATE : 46803 nodes read in 1 seconds xorriso : NOTE : Detected El-Torito boot information which currently is set to be discarded Drive current: -indev '/gnu/store/v13bryy1mrgrs694drsrknryf204q30j-image.iso' Media current: stdio file, overwriteable Media status : is written , is appendable Boot record : El Torito , MBR protective-msdos-label grub2-mbr cyl-align-off GPT APM Media summary: 1 session, 473456 data blocks, 925m data, 45.6g free Volume id : 'GUIXSD_IMAGE' xorriso : NOTE : Tolerated problem event of severity 'SORRY' Report layout: xt , Startlba , Blocks , Filesize , ISO image path File data lba: 0 , 8612 , 720 , 1474560 , '/efi.img' File data lba: 0 , 25032 , 0 , 0 , '/gnu/store/1zzgag2ca7xzklss2j6phh4580cgkbl2-flac-1.3.2/share/doc/flac-1.3.2/FLAC.tag' File data lba: 0 , 25032 , 0 , 0 , '/gnu/store/55m1dng1zw7fq7ni73nm2v7b84wghpka-libx11-1.6.6/share/X11/locale/am_ET.UTF-8/XI18N_OBJS' File data lba: 0 , 25032 , 0 , 0 , '/gnu/store/55m1dng1zw7fq7ni73nm2v7b84wghpka-libx11-1.6.6/share/X11/locale/cs_CZ.UTF-8/XI18N_OBJS' File data lba: 0 , 25032 , 0 , 0 , '/gnu/store/55m1dng1zw7fq7ni73nm2v7b84wghpka-libx11-1.6.6/share/X11/locale/el_GR.UTF-8/XI18N_OBJS' File data lba: 0 , 25032 , 0 , 0 , '/gnu/store/55m1dng1zw7fq7ni73nm2v7b84wghpka-libx11-1.6.6/share/X11/locale/fi_FI.UTF-8/XI18N_OBJS' File data lba: 0 , 25032 , 0 , 0 , '/gnu/store/746645dl4fmz9h12x247nyznalswqyzp-groff-minimal-1.22.3/share/groff/1.22.3/tmac/mm/locale' File data lba: 0 , 25032 , 0 , 0 , '/gnu/store/746645dl4fmz9h12x247nyznalswqyzp-groff-minimal-1.22.3/share/groff/1.22.3/tmac/mm/se_locale' File data lba: 0 , 25032 , 0 , 0 , '/gnu/store/a1vpwa7wkxbxw18sz70rmp3cdfnf3jdj-libvorbis-1.3.6/share/doc/libvorbis-1.3.6/doxygen-build.stamp' File data lba: 0 , 25032 , 0 , 0 , '/mach_kernel' File data lba: 0 , 25034 , 1173 , 2400500 , '/boot/grub/fonts/unicode.pf2' File data lba: 0 , 26207 , 1 , 1520 , '/boot/grub/grub.cfg' File data lba: 0 , 26207 , 1 , 1520 , '/gnu/store/3zq39lvf12a87zcfrg87xgkllgfsyw3b-grub.cfg' File data lba: 0 , 26208 , 5 , 9928 , '/boot/grub/i386-efi/acpi.mod' […] File data lba: 0 , 475300 , 1 , 1651 , '/gnu/store/zrg4c2d0lvyw8z9xgh0darzglbxrm6b7-iptables-1.6.2/share/man/man8/iptables-restore.8.gz' File data lba: 0 , 475301 , 1 , 1137 , '/gnu/store/zrg4c2d0lvyw8z9xgh0darzglbxrm6b7-iptables-1.6.2/share/man/man8/iptables-save.8.gz' File data lba: 0 , 475302 , 4 , 7837 , '/gnu/store/zrg4c2d0lvyw8z9xgh0darzglbxrm6b7-iptables-1.6.2/share/man/man8/iptables.8.gz' File data lba: 0 , 475306 , 47 , 96256 , '/System/Library/CoreServices/boot.efi' File data lba: 0 , 475353 , 1 , 236 , '/System/Library/CoreServices/SystemVersion.plist' File data lba: 0 , 475354 , 1 , 1399 , '/System/Library/CoreServices/.disk_label' File data lba: 0 , 475355 , 1 , 10 , '/System/Library/CoreServices/.disk_label.contentDetails' File data lba: 0 , 475356 , 88 , 180224 , '/var/guix/db/db.sqlite' xorriso : NOTE : -return_with SORRY 32 triggered by problem severity SORRY --8<---------------cut here---------------end--------------->8--- Something’s fishy, and Xorriso is sorry. :-) Let me know if I can provide more info.

Something seems to be wrong with the > system clock of the producer machine. For reproducibility purposes we set timestamps and related things to the Epoch. This pseudo-UUID/timestamps is actually derived from the config of the operating system in the image. It’s expected. :-) Thank you! Ludo’.
