[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [OSSTEST PATCH 24/62] overlay-persistent-net: Copy from jessie
These were copied from a system running Debian jessie.
The nontrivial files are:
# Copyright (C) 2006 Marco d'Itri <md@xxxxxxxx>
# Copyright (C) 2007 Kay Sievers <kay.sievers@xxxxxxxx>
and licenced GPLv2+. That is compatible with osstest's AGPLv3+.
Right now we do nothing with these.
