In recent times i have confined /usr/bin/cgclear but i later decided to undo it (it is probably in my "git log" though).

cgclear isnt such a problem to run confined but this app can also be run by users.

A similar app is cgexec this program basically "extends" init script, but it can also be used to users.

Confining both cgclear and cgexec is possible but it make thing probably more complicated then they need to be.

There are other cg apps called from cgconfig init script as well like: cgset, cgclassify, cgcreate. These are really /usr/bin user apps.

Looking at the initrc policy, initrc has pretty much access so i personally do not have a problem adding this as well to avoid unneeded complications.\x18
