The hostname -f option is a "new-ish" Linux specific option.  It's not
portable.  And because it works by doing a reverse DNS lookup it
depends upon live network connectivity at that moment working for the
network lookup and the results are spotty depending upon how DNS is
set up and how many IP addresses are configured on the host.

It's problematic.
