I've decided not to use --invariant, because Thomas Schmitt wrote that it is important to have unique IDs for /dev/disk/by-label. So I've converted the SOURCE_DATE_EPOCH to hex (which is 32bit until 2038) [which I should have done when I introduced the -i command line argument. :-) ] See MR243 https://salsa.debian.org/live-team/live-build/-/merge_requests/243 With kind regards, Roland Clobus
