From 7d7017a583a014c239cf8f68d484f22f67ca80ac Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Zbigniew=20J=C4=99drzejewski-Szmek?= Date: Fri, 11 Nov 2016 10:54:54 -0500 Subject: [PATCH] basic/virt: fix userns check on CONFIG_USER_NS=n kernel (#4651) ENOENT should be treated as "false", but because of the broken errno check it was treated as an error. So ConditionVirtualization=user-namespaces probably returned the correct answer, but only by accident. Fixes #4608.
