From e93072374112db9dc86635934ee761249be28370 Mon Sep 17 00:00:00 2001 From: Casey Schaufler Date: Thu, 1 Nov 2012 18:14:32 -0700 Subject: Smack: create a sysfs mount point for smackfs There are a number of "conventions" for where to put LSM filesystems. Smack adheres to none of them. Create a mount point at /sys/fs/smackfs for mounting smackfs so that Smack can be conventional.
