As discussed here: https://github.com/fail2ban/fail2ban/issues/1593, the monitored file has to be present before the fail2ban service starts. Create this file in a dedicated activation service. * gnu/tests/security.scm (%auth-log-activation-service): New variable. (run-fail2ban-basic-test, run-fail2ban-simple-test) (run-fail2ban-extension-test): Use it. Fixes: guix/guix#3645 Change-Id: Ic12891cc5438abbd041ceb19e1d22dae51c7c848
