Comment:
> Void has alertmanager with v2 API packaged since Feb 5 2019, so I don't think this needs an install message.

Sure, I only included it here because it seemed like the biggest change in the package, doesn't need to be an install msg.

> The xlint message is a false positive, vlicense NOTICE isn't installing the Apache-2.0 license, but license notices for other components (Bootstrap, jQuery, LevelDB, etc).

Might be nice to add a comment above the `vlicense` then. I think adding them all to `license=` would get too noisy.
