I have written a renew-hook for letsencrypt, and it does not need
SRV records.
It seems to work but I have limited facility/ability to test.
If there is anybody out there interested would they try it, test it and let me know whats wrong with it.
Its a bash script, and should probably be rewritten in something
a little more tamper proof. I am currently brushing up on my C++
and looking into Python, suggestions as to language welcome.
