etckeeper integration

I'd like to get etckeeper (http://etckeeper.branchable.com/) to track the history of my system configuration, however there is no native support for Alpine Linux currently.

Are there any hooks that I can setup so that I can automatically catch pre/post package installation/uninstallation stages... or would I have to such a hook system into apk (presumably using something like /etc/apk/{post,pre}-{install,uninstall}.d directories to make a more useful generic system).
