From 8dd0a45c858290288e1a1fef046b5cfcf7ff6257 Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Mon, 22 Nov 2021 16:11:45 +0000 Subject: nativesdk: Handle chown/chgrp calls in nativesdk do_install tasks We disable the useradd code for nativesdk targets since we don't support postinstalls or multiple users in those cases. This means any usage of chown/chgrp inside do_install tasks won't work and would have to be conditional. Rather than require all recipes to do that, add intercepts of the calls and map those to root/root user/groups. We can't just ignore them as some calls are used to remove host contamination from the host user ID so they need to be made, just as root.
