Subject: seobject_fcontext patch allows you to modify a preexisting file context.
Date: Fri, 07 Nov 2008 09:46:36 -0500

Currently semanage is not allowed to change a file context mapping if it
matches exactly,  this patch allows you to modify the file context.

Signed-off-by: Joshua Brindle <method@manicmethod.com>

NOTE: original patch modified to remove unused list in fcontext get_all()
