In my experience on ext4 (also not backed by looking at the code), "guix gc" always deletes substantially less than what I ask for. I always thought it just counted hard linked files even when the link count does not go to 0 and the file is not actually deleted. For instance, I have tried it just now: $ df -h . /dev/mapper/cryptroot 468G 427G 18G 97% / $ guix gc -F 20G guix gc: 2.931,84 MiB werden freigegeben ... deleted or invalidated more than 3074252800 bytes; stopping $ df -h . /dev/mapper/cryptroot 468G 427G 18G 96% / Andreas
