File_t is an unlabeled file.  The kernel looks at the extended
attributes of a file for its file context, if none are found it reports
it as file_t.  The only way you should be able to get a file_t is if you
put in an unlabeled file system and moved the file over.  This should
not happen ordinarily.  Also you can fix the file labels with a
restorecon/chcon call rather then a full relabel, or you can just delete
the file.


Is this file being created from a virtual machine?  How is this file
getting there?
