[Letsencrypt-devel] Bug#825732: certbot: Wrong cron execution

[Archi]

Package: certbot
Version: 0.6.0-2
Severity: normal
Tags: patch

Dear Maintainer,

After default install of certbot package, there is /etc/cron.d/certbot created with default setting of * */12 * * *.
As upstream suggests, renew should be done twice per day, instead, according to above cron, it's executed every minute of 12 and 0 hour.
Instead, it should execute at 0:00 and 12:00, this way already included random will ensure that it's run twice - between 0:00-1:00 and 12:00-13:00.
Patch is included in changed configuration files. Thank you.
