Subject: guix system roll-back doesn't roll setuid-programs back
Date: Fri, 3 Jan 2020 01:48:03 +0100

Steps to reproduce:

1. Add a setuid program to your config:

(setuid-programs (cons*
                   (file-append hello "/bin/hello")
                   %setuid-programs))

2. guix system reconfigure
3. Observe that /run/setuid-programs/hello got created
4. Undo the configuration change
5. guix system reconfigure
6. Observe that /run/setuid-programs/hello no longer exists
7. guix system roll-back

Expected behavior:
/run/setuid-programs/hello appears again

Actual behavior:
/run/setuid-programs/hello still doesn't exist

Similarly, when roll-back is supposed to remove a file, it doesn't.
