problem wiath a sysmlink warning

[jim]

Hi;
I'm new so I'm sure this is just something I'm overlooking. (yes, I tried to google for it)

I get the following with gradm -C

Warning: permission for symlink /var/run in role root, subject /sbin/service does not match that of its matching target object /. Symlink is specified on line 173 of /etc/grsec/policy.

I'm not sure what is causing it and could use some help. Relevant parts of my policy is listed belowL

Hi Jim,

Most likely, as /var/run is a symlink (probably to /run) you'll want to add a "/run rwcd" line to the /sbin/service subject.
