Is apk a classic package manager in that it installs packages to the file system or does it use overlays?

The line

> Alpine Linux is designed to run from RAM

in the wiki almost makes it sound like OpenWRTs opkg where the root fs is readonly.

Alpine can do both, actually; a "sys" install does a traditional root filesystem, but Alpine also can run... I think a ro root with a single rw overlay with all added packages(?)
