I have made several pkgsrc entries for use on Linux systems.

Hopefully, soon I will have a self-hosting Linux systems that all software
is installed via NetBSD packages!

I will PR these after I fully test under NetBSD too. (Or mark that they
don't work under NetBSD.)

(Note for GNU ed(1) pkgsrc, please set GNU_PROGRAM_PREFIX to what you
want. I set it to nothing.)

I also have:
misc/linux-kernel -- not finished
misc/man -- not finished

Also, net-tools has hostname(1) and so does sh-utils. I'll need to pick
one.

Soon I will pkgsrc-ize a mailx(1) (probably NetBSD's mail(1)), modutils,
MAKEDEV script (for Linux), and a few basic, ready-to-use /etc configs.

Also, I plan on adding a variable for when set it will also setup build or
regular dependencies for common stuff, like libc and regular, basic shell
tools.

And maybe I will add a variable when set and only used for a small amount
of packages, these packages will also install copies directly to a /bin
and /sbin (and modify PLISTs accordingly).

Anyways, please send your feedback.

Does anyone want to help?

Does anyone have a Linux system we can test on and do some bulk builds?

Can anyone test these under another OS?

p.s. BSD is so much easier! Chasing down all these "base" tools has not
been fun. I see there are various different versions, maintained by
various people (or projects) with patches every which way. It is
interesting to note that some non-Debian-based distributions actually use
Debian tarballs and diffs, because the original code is so poorly
maintained.
