4Subject: [PATCH weston] weston-launch: Provide a default version that doesn't
5 require PAM
6
7weston-launch requires PAM for starting weston as a non-root user.
8
9Since starting weston as root is a valid use case by itself, if
10PAM is not available, provide a default version of weston-launch
11without non-root-user support.
