I looked through the Open Group documents that the letters you sent me
pointed to. I'm not clear on whether it's required to reject unknown
arguments starting with a - but not after a --. That would significantly
influence my implementation -- I would prefer to have hostname work like
this:
hostname foo.bar.com
Sets the hostname
hostname --fqdn
retrieves the hostname as an FQDN
hostname -f
ditto
hostname --long-option-I-never-heard-of
rejected with a usage message
hostname -- --long-option-I-never-heard-of
sets the host name to --long-option-I-never-heard-of
But I'm wondering if there might be a reason that coreutils's "hostname"
recognizes
--help and --version but takes --anything-else as being a hostname. Is
there a reference that implies that the current behaviour is preferred?

I'm hoping someone will submit a patch :-)

These two give most of the details.

This is becoming a FAQ.
