From 272d243e00c742f9cffc8bc46d09b7d0f19dc43e Mon Sep 17 00:00:00 2001 From: =?utf8?q?Kristian=20H=C3=B8gsberg?= Date: Tue, 29 Jan 2013 14:14:06 -0500 Subject: [PATCH] weston-launch: Clear environment and set it up from scratch With recent systemd[1] XDG_VTNR will leak through to pam, which ends up setting a vtnr pam argument with the wrong value. The fix is to clear XDG_VTNR first, but what we should have been doing all along is resetting the environment. Thanks to Ray Strode for helping debug this.
