Alpine Linux has switched to musl libc

I am happy to announce that our ‘edge’ branch is now using musl libc.

Edge users you will have to do this to migrate:

1. Edit /etc/apk/repositories and make sure that you don’t mix edge and any stable branch (eg v2.x)
2. Install static apk-tools and busybox. This is a safety net in case things goes wrong. apk add -U apk-tools-static busybox-static
3. Run a simulation. This will show what will happen: apk.static upgrade —no-self-upgrade -U -a —simulate
4. Perform the actual upgrade: apk.static upgrade —no-self-upgrade -U -a
5. Reboot.

After this your system should be running musl.

The uclibc edge repos are still available but as ‘edge-uclibc’ instead of ‘edge’.
