[arch-dev-public] Adding a "posix" metapackage

3 Jan 2020

      After a bit of research work and making sure one or two things have been
properly packaged, I've developed a PKGBUILD which ensures that a system
has the POSIX shell and utilities (XCU) section installed. I believe
this is an interesting thing to track, and people will want to know they
have it installed... in aid of this, I've gotten two major holdouts
packaged a while back -- pax (thanks to dbermond) and ncompress.

I'd like to add this package to community, although given it's never
been in the AUR before, it's never had AUR votes...

One of the advantages of having this metapackage is that someone can,
while installing arch, `pacman -S posix-user-portability` and get
essentially everything one would expect to have available on a unix-like
platform, most notably, the interesting parts of the base group that no
longer have an equivalent. i.e. man-db, vi, patch, diffutils, ed.

I've only included XCU for now, because the system interfaces and
headers are a bit out of scope for me to package and replace in the
event that they'd be missing anything... and also because I'm mainly
interested in the POSIX toolset itself. That being said, I'd certainly
be open to suggested improvements, should anyone have recommendations
for expanding the scope.

Thoughts?

For reference, here is my PKGBUILD: https://paste.xinu.at/m-XoggqFGE/
And reproduced here:

# Maintainer: Eli Schwartz <eschwartz@archlinux.org>

# The list of utilities can be found at
# https://pubs.opengroup.org/onlinepubs/9699919799/idx/utilities.html

# Not all utilities are required: if the synopsis is boxed up and annotated
# with a code, it is only needed for that code. Examples: user portability,
# XSI, Software Development, C Development. Some of these groups were
# implemented here too, though almost certainly the only important ones
are UP
# and XSI.

         - The SCCS development tools are not available, but may be obtained
           from the AUR in the event you believe anyone still uses it.
         - The cflow package can likewise be obtained from the AUR.
