The idea here is to discourage any prolonged use of the default 
self-signed certs at all, as they don't provide full protection from 
MitM attacks. That's why the 30 days validity period was suggested 
(compared to current 10 years) and discussed during the meeting. Adding 
an auto-regeneration feature would be going directly against that idea, 
so I personally wouldn't vote for that.

I'd say that in such context, you'd be using one of the configuration 
management systems (Puppet/Chef/Salt/Ansible/homegrown scripts/whatnot) 
anyway, as that's a standard system administration BKM, so IMHO that's a 
reasonable assumption at the OpenBMC project end that it's not going to 
add any noticeable burden for BMC admins.
