From b654a1065f278c93b3891cc5993645026e0d3702 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Fri, 4 Jul 2014 03:10:09 +0200 Subject: [PATCH] units: conditionalize configfs and debugfs with CAP_SYS_RAWIO We really don't want these in containers as they provide a too lowlevel look on the system. Conditionalize them with CAP_SYS_RAWIO since that's required to access /proc/kcore, /dev/kmem and similar, which feel similar in style. Also, npsawn containers lack that capability.
