golang-github-rootless-containers-proto-dev 0.1.0-2 (amd64 binary) in ubuntu lunar

 This project contains the protobuf definition of the user.rootlesscontainers
 extended attribute. The main purpose of this attribute is to allow for a
 interoperable and standardised way of emulating persistent syscalls in a
 rootless container (syscalls such as chown(2) which would ordinarily fail).
