Likewise, generated files such as Makefiles would have captured the ….drv name. Like Mark writes, it’s not the end of the world: you can simply rename /tmp/guix-build-….drv-0 to /tmp/guix-build-….drv. However, it means that things would be inconvenient by default, which doesn’t sound great to me. WDYT? Thanks, Ludo’.
