No easy way to find out which version of a package is installed
For example: apk info mesa-dev outputs the info from all versions available with no indication which one is installed, apk info --installed mesa-dev just outputs me mesa-dev and nothing else. But I can use apk list --installed mesa-dev and it gives me the information I want: mesa-dev-9999-r8 aarch64 {mesa} (MIT SGI-B-2.0 BSL-1.0) [installed]
