There was two forgotten file instances. Fix error such as:
/root/tmp/rpm-tmp.80ZNEF: line 1: /usr/sbin/post_service: No such file or directory
error: %post(traefik-2.4.14-alt1.x86_64) scriptlet failed, exit status 127
error: traefik-2.4.14-alt1.x86_64: install failed
Fixes: 5ef5c8ff4 ("Use file4 instead of file")
