So for completeness I managed to reproduce the issue with the same ZFS settings as upstream: echo 1 | sudo tee /sys/module/zfs/parameters/zfs_bclone_enabled sudo zfs set recordsize=128K tank/build And I made double sure the build was done on that drive too: export TMPDIR=/tank/build/tmp mkdir -p "$TMPDIR" dpkg-buildpackage -us -uc -b > Once upstream releases a new version I will attempt to get it into Debian > fairly quickly, or would you like it > sooner and for me to backport the patch ? Upstream has released a new version with this fix; and it no longer FTBFS on ZFS for me ! I will upload it into the archive soon. Cheers! Chris
