But you might need to subvert another part of the system to accomplish this.
Being paranoid, it is always a good idea to at least make sure that there is
no symlink where you want to create your file. The easiest way to accomplish
this is to remove it before. If selinux cannot cope with that, that's a
selinux problem. Fix it there.

It depends on what service you can get to act up. Additional paranoia is
always good. :-)
