New comment by loreb on void-packages repository https://github.com/void-linux/void-packages/pull/40063#issuecomment-1710072274 Comment: I can think of a few disgusting hacks (say, making two pairs of identical packages, such that sybil is tested with fixtures-dummy, fixtures is tested with sybil-dummy, and the -dummy packages have their do_check be a NOP), but no clean solution either. Can you try asking on IRC/reddit?
