I generally prefer Gentoo's method: /var/lib/portage/world for manually installed packages, /var/lib/portage/world_sets for selected sets, and sets can be defined in /etc/portage/sets/. This allows you to split your packages into categories and only install certain bits on systems where you need them, as well as add any comments to the files as necessary. The equivalent to `apk fix` is `emerge -uDU @world && emerge -c` which is slightly more unwieldy but oh well. Alpine allows something akin to sets by using `apk add -t setname pkg1 pkg2 pkg3`, which creates a dummy package which depends on your package selection. I generally create shell scripts in /etc/apk/sets/ to mimick the Gentoo experience, but it's not always the same.
