From 94838def772349387e16cc642b3642020e22deda Mon Sep 17 00:00:00 2001 From: Gonéri Le Bouder Date: Thu, 12 Mar 2020 14:37:08 -0400 Subject: Add Netbsd support (#62) Add support for the NetBSD Operating System. Features in this branch: * Add BSD distro parent class from which NetBSD and FreeBSD can specialize * Add *bsd util functions to cloudinit.net and cloudinit.net.bsd_utils * subclass cloudinit.distro.freebsd.Distro from bsd.Distro * Add new cloudinit.distro.netbsd and cloudinit.net.renderer for netbsd * Add lru_cached util.is_NetBSD functions * Add NetBSD detection for ConfigDrive and NoCloud datasources This branch has been tested with: - NoCloud and OpenStack (with and without config-drive) - NetBSD 8.1. and 9.0 - FreeBSD 11.2 and 12.1 - Python 3.7 only, because of the dependency oncrypt.METHOD_BLOWFISH. This version is available in NetBSD 7, 8 and 9 anyway --- cloudinit/distros/bsd_utils.py | 50 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 50 insertions(+) create mode 100644 cloudinit/distros/bsd_utils.py (limited to 'cloudinit/distros/bsd_utils.py') diff --git a/cloudinit/distros/bsd_utils.py b/cloudinit/distros/bsd_utils.py new file mode 100644 index 00000000..079d0d53 --- /dev/null +++ b/cloudinit/distros/bsd_utils.py @@ -0,0 +1,50 @@ +# This file is part of cloud-init.
