[Buildroot] [PATCH] openresolv: new package

[Matt Weber]

From: Paresh Chaudhary <paresh.chaudhary@rockwellcollins.com>

This patch added 'openresolv' package support. This tool
provides a dns management framework to track currently
available nameservers.

A key feature of this tool vs resolvconf is the ability to
manage multiple name server input configuration files and
generate the /etc/resolv.conf.  This is handy when you have
multiple dynamic communication paths providing nameserver
information.

Are you sure it needs a bash shell ? Indeed in
https://github.com/rsmarples/openresolv, the #1 argument for resolvconf
compared to its Debian variant is:

""
Works with POSIX shell and userland
""

> $(eval $(autotools-package))

This package is not using the autotools. The configure script is not
generated by autoconf, the Makefile is not generated by automake. So,
generic-package should be used, and not autotools-package.

Thanks!

This dialog should have been included in the description related to
use of getopts vs getopt in the script.

https://github.com/rsmarples/openresolv/commit/a694a49c41ffdc0e215320459af009d44482b065#commitcomment-29850615

Missed this, looks like they are mimic'n a configure script.  It is
working as a autotools pkg, but I'll pull the commands over to a
generic.

I think Paresh got it wrong somehow. Busybox provides both getopt and
getopts. getopt is non-POSIX, while getopts is POSIX (see
https://en.wikipedia.org/wiki/Getopt#Shell and
http://pubs.opengroup.org/onlinepubs/9699919799/utilities/getopts.html).

Minimal Buildroot system with our default Busybox configuration:

# getopts
-sh: getopts: usage: getopts optstring var [arg]
# getopt
getopt: missing optstring argument

Both are provided. getopt is a separate program, getopts is a shell
built-in.

I added a comment on the Github issue.

Please don't pull the full commands from autotools-package with all the
environment variables and options that only make sense for
real-autotools based packages: only include the minimal set of
variables/options.

Thanks!
