Looks good and works for me. Thanks for submitting!

I think i've been added by accident so i'll accept the revision to not stand in the way of the process :)

Looks good,

I actually wanted to wait for the next tag just to see how often things get tagged before abandoning the current versioning scheme. Also there is not much of a difference between the ports version and the tagged 0.1.0. But i think if need be we could go with an interim version like 0.1.0.xxxxxxx, so go ahead and commit it.

Looks good to me, feel free to commit.

The periodic script is missing a "then" in the last if clause which results in a sytax error:

The call in the periodic script does nothing if the configured max age of the certificates isn't reached.
So the only thing this changes for existing users is that they can be more granular with their age settings.
One could make a case to do this daily as the age is configured in days but i think a week is good enough.
If not this can be fixed with another update if enough users need this.

Thanks for the additions! Please commit.

I've no objections to the proposed changes but I still have an update request open here:
