This is neat and it should be part of 9legacy soon.

The 9front git mirror is just that, a mirror of git.9front.org.
I updated stuff to have github actions for syncing largely because
the 9front github org already existed, and github is currently the easiest
way to get free on demand windows and mac hosts to build your stuff.
Since the repos existed I figured they might as well be up to date.

The important thing to consider here is that the main 9front repo is
what we use for updating the install, our sysupdate script is a small
wrapper around git/pull. I would like to avoid adding extra things in
the repo in order to accommodate things like this, they don't really
have a place in the 9front source tree.
I would encourage someone to do this work for 9front as a separate repo;
git submodules or some scripts or whatever floats your boat for referencing
both repositories. I considered doing this myself for the 9front-in-a-box
repo, but my plate is full for the near future.

9front has a strong desire to dog food our own code. I think this is a pretty
important distinction between our project and many other hobbyist operating systems.
We were lucky to inherit a lot of this from Plan 9, but further improvements have
been done to continue this desire. We've lost count of the nasty bugs we found
by actually putting the system to use. Many of purposed improvements to the system
come out of desires that people have when just using the system day-to-day.
There is a certain zen of Plan 9 that you don't fully grasp until you immerse
yourself in the entire picture, editors and window managers included.

While I understand the desire to make things easier for people to bring their
own set of presumed tools with them to work on 9front, I think there is an
established history of Plan 9 rejecting that. Asking people to take off their
coat and stay a while.

Just my two cents on the matter, I put in some thought in about this after Russ
did this work for 9legacy.

sorry to disagree moddy, but we already document how to use qemu in
the 9front fqa. qemu virtualized amd64 is one of the easy ways to boot
up a real 9front kernel, so i wouldn't say we don't support this
"target".

i'm happy to see other plan9 folks have returned to actually booting
real plan9 kernels, even if it's just on a virtualized pc.
if this goes on people will realize plan9 is more than just a text
editor (acme) or a filesharing network protocol (9p).

this is something i didn't know about until now:
guestfwd=tcp:10.0.2.1:564-cmd:../sys/src/cmd/unix/u9fs/u9fs -a none -u $USER ..

so, thanks.

i also see no reason to reject alien scripts (bourne shell) that help
create compatibility. there's no real cost. right now we maintain
something like this in the fqa, which is bigger overhead (.ms
formating is painful) and less directly usable (cannot be directly
executed) by the user.

the same cannot be said about submodules. there is significant cost
for everybody who has to use repos containing submodules.

That’s not my goal at all sorry for the misunderstanding.

sounds like a good idea. however it would be called, i'd put it next to ape.

sounds good.
i would not try to generalize linux/alien/ape stuff too much as there
are too many distros, but whoever has a tested-working thing for
whatever linux toy might help others by example at the very least.
often it's the same for all relevant distros: most should ship pretty
much the same qemu/kvm interface.

i'm not gonna pretend this leads to great quality, but low-tier help
for alien interop. is better than none.

> Who is going to maintain those scripts and test them regularly?

only a linux user can maintain them. maybe documentation should
mention they frequently become unmaintained, out of date, like we are
also used to with ape. it might help to document which linux distro
and version it worked with at some point.

imo test-driven development is extremely overrated, and mostly
implemented only superficially.

I dont see CI testing them at all. Sounds way too complicated.

Should we also test ape/equis/vt/ssh? all this just dips in way too
deep in the magma lakes of alien computing interoperability hell.
some of this is surprisingly well maintained lately, but full
end-to-end tests would require too much complexity, and even more
alien hell.

as long as users don't expect too much of it, as long as it's
separated in another directory, it should be easy to ignore.

over 3/4 of plan9 code is just dealing with messy alien stuff like
non-plan9 computing. interoperability is difficult.

we give a lot of space to the kinds of stuff you are criticizing in
the fqa, i suppose in your view this is not a problem because it's a
different repo?

if your priority is make sure that all the stuff is well tested, i
feel that in the fqa it's harder to test bec. copy&pasting into and
out of the fqa is a bit more tedious than running a script that's
already in a folder somewhere. with the fqa you often end up testing
your quoting/unquoting and copy&pasting skills instead of the actual
code.

> I want the 9front repo to be primarily for use by 9front machines.

this sounds like an interesting request, just i don't see us drawing a
very clear line.
