Anyone using 6-day certs yet? (self.selfhosted)

Since the beginning of this year, Let's Encrypt rolled out a new shortlived profile for certificates that make them valid for only 160 hours. The intention, as they say, is to encourage automation and reduce the window of certificate compromise (because revocation is somewhat a flakey thing).

Yet, I haven't seen a lot of news about it since then. Hence the question: is this shorter cert thingy something you considered and deployed for your homelab?

As for me I've set up lego-acme with profile: "shortlived" on my rig. Lego runs on a bihourly cronjob, but only renews when a cert has >=3 days to expiry. It's been pretty much a set-and-forget experience, although some more monitoring would be nice.

I don't know what the BFD is. Noone is supposed to handle certs manually anyway. OK, maybe companies that did not get the message but nowadays this is supposed to be automated and then it does not really matter whether the cert is valid for 90, 45, 30, or 6 days.

For security, it does matter, shorter is better.
