Code review comment for ~dashmage/charm-logrotated:bug/2017798-update-cron-daily-location

Have you considered using a mature library (e.g. python-crontab [1]) to interact with crontab? I'm a bit worried that there are some consequences we have not considered when directly overwriting the cron file.
