But this is a bit odd, and one of the use of /proc/cgroups is to check if a subsystem is supported or not, so we can no longer do this: #! /bin/sh grep -q debug /proc/cgroups if [ $? -ne 0 ]; then echo "debug subsystem is not compiled into kernel" exit 1 fi # mount debug_subsys and do something with it... _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
