I initially tried to, with "nix-store --delete FILE.drv". But Nix
complained that they were "live". Now I used more force, "nix-store
--delete --ignore-liveness FILE.drv" and it seems to work. But isn't
it a bit "lucky" that the files weren't in use? According to the
nix-store man page, --ignore-liveness will be ignored if the path is
referred to by other paths.
