Description Brian G. Anderson 2007-12-03 18:43:16 EST
Description of problem:
I get a regular stream of selinux warnings from my mounted encfs system.  See below.

    SELinux is preventing encfs (xdm_t) "getattr" to /boot (boot_t).

Detailed Description
    SELinux denied access requested by encfs. It is not expected that this
    access is required by encfs and this access may signal an intrusion attempt.
    It is also possible that the specific version or configuration of the
    application is causing it to require additional access.

Allowing Access
    Sometimes labeling problems can cause SELinux denials.  You could try to
    restore the default system file context for /boot, restorecon -v /boot If
    this does not work, there is currently no automatic way to allow this
    access. Instead,  you can generate a local policy module to allow this
    access - see http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385 Or you
    can disable SELinux protection altogether. Disabling SELinux protection is
    not recommended. Please file a
    http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against this package.

Looks like this bug doesn't concerned with encfs but rather with selinux policies.

You should adjust your selinux policies. Take a look at the following articles
(just for starting point):
