LUDOC-117 style: use <replaceable> in example text

Use the <replaceable> tag and {} instead of <emphasis> and
<> for user-supplied text.  The XML markup is intended to
be semantic, so <replaceable> is more correct to use.

The use of <> makes the XML ugly, since it needs to be
written as &gt;&lt; in the .xml files.

Some incorrect usages of <emphasis> were corrected.

Update the documentaion to store module parameters in the

Early versions of modprobe did not care what filenames were

versions of files were located there (e.g. Lustre.orig or
Lustre~).  Newer versions of modprobe (at least since FC12,
but possibly earlier) require module parameter files to have
a ".conf" suffix in order to be parsed.

The /etc/modprobe.d/ directory has been supported since at

before that time.  This means that all supported distros can
