I take the approach of editing and formatting the magic used by file and
exclude the file package from updates (exclude=file in /etc/yum.conf).
It's quite a simple process - the flat file and compiled binary data are
at /usr/share/file/ read the man page for file(1) for details of
compiling the magic. Copy the /usr/share/file/magic to /tmp, edit to
your taste and then "file -C -m /tmp/magic" to compile it. Make sure you
keep a copy of your edited magic file somewhere as its really annoying
when rpm overwrites it!
the edits that I make are simply to comment out 5 lines that identify
Apple Quicktime movie files where the first four bytes spell out a word
or a start of a word (free, junk, skip, wide and pict). So far QT is the
only false positive I've had to deal with but the same approach can be
used for others.
