# Changing ownership and user rights to support following use-cases:
# 1) running container on OpenShift, whose default security model
#    is to run the container under random UID, but GID=0
# 2) for working root-less container with UID=1001, which does not have
#    to have GID=0
# 3) for default use-case, that is running container directly on operating system,
#    with default UID and GID (1001:0)
# Supported combinations of UID:GID are thus following:
# UID=1001 && GID=0
# UID=<any>&& GID=0
# UID=1001 && GID=<any>
