Include:Upgrading to Edge

An upgrade of Alpine Linux from a stable version to the rolling development version, edge can be done in a few simple steps.

1. Add the edge repository to /etc/apk/repositories:

   echo http://dl-3.alpinelinux.org/alpine/edge/main >> /etc/apk/repositories

   or just edit the file in-place (replace v2.4 with your release):

   sed -i -e 's/v2.4/edge/g' /etc/apk/repositories

2. Upgrade all packages in one shot:

   apk upgrade -a -U

3. Check your current release:

   cat /etc/alpine-release

   You will see the build date attached to the release.
