working on an opensmtpd service using guix records

[Joshua Branson]

Hey guix,

I have been working on extending the current opensmtpd service using
guix records.  The code is here:

https://notabug.org/jbranso/linode-guix-system-configuration/src/master/opensmtpd-records.scm

It's pretty work in progress.  I'm not using it on my guix server yet.

Incomplete documentation and my various thoughts about the service are
here:

Some videos of me coding it are here:

Consider this a public service annoucement.  If someone else is
already working on this, then let's do it together!

Thanks,

Joshua
