Thanks for your input, Efraim.
Do you happen to know why guix in the situation I described,
being on an up to date branch following master refuses to build,
but once I switch to master branch, make clean, make clean-go (or
go-clean?) and run make (and the other commands) again it builds
successfully? This was my initial confusion.
I might have a thing or 2 to learn about rebasing and branching, but in
theory from what I know it shouldn't really matter which branch I am
on unless something's corrupted or broken.

Re: developing for guix with git

[Nils Gillmann]

I hope I can turn my current confusion and the notes I am taking to
something productive to beginners documentation/guide at some point.

So what happened today was:
- I tried the build of the sourcetree described below in some
variations. Failed.
- I mounted an external disk with what used to be my working repo of the
source before I made the decision to not rely on external disks that
much. switched to some branch on this disk I was working on, excluding
problems with the file I was working on it did theoretically build.

Now I wonder what could be the difference? Why does my current checkout
fail, but the other one doesn't?

iirc the current one went:
git clone $url-on-sv-guix
git checkout -b wip-lispf4
emacs gnu/packages/lisp.scm and work on that file, save it but not
commit
guix environment guix (also tried adding git make)
make clean-recursive
./bootstrap
./configure --localstatedir=/var
make check

what would be a simple step by step command list to get to the point of
a working branch which can build?

I feel like I am asking weird questions and it might be that I just try
too much too hard to see where the problem is so that I lost track of
the actual problem.

I am not sure.
Adding to the Email I just wrote to this thread, how would I do this?
Isn't 'guix environment guix git' taking care of that already?
Or is this git-fetch message entirely related to the file (lisp.scm) I am
working on where I might have forgotten to add (guix git-download)?

I'll investigate further tomorrow.

Thanks,

I see. Okay, I'll try that and see if world builds again successfully.

I might've been preoccupied due to being a bit ill and not fully capable
in understanding what I am doing, I guess. I dislike giving answers
which are shorter than the actual message, but thanks for helping ill-me
so far. I hope this solves the problem I had.

Okay, I do understand now that if "make check" fails with some errors,
those are related to a file I am working on and that fixing those errors
lets "make check" pass. If one thing is broken, everything falls.
This might be information I know when I am not ill. Good that I did
waste some days on this. Problem seems solved now, by reading more into
sources.

Hi,

there's hnode.org and some other pages covering it I don't have
at hand at the moment. If you have no problems with dongles and
maybe want it to use for future purposes as an WiFi AP, you could
get TP-Link TL-WN722N, v1.10 works with linux-libre (personally
tested) and there are some more resources on this out there.

How can I test better?

[Nils Gillmann]

Regarding:
https://lists.gnu.org/archive/html/guix-devel/2016-02/msg00313.html

I wonder how I can be sure if `guix environment` does not give me
a 100% reproduction of what is happening with the files later on,
how can I verify what I push as patch does work and which doesn't
if I have to write the install procedure of `make` myself?
Is `guix system vm` better?
How can I test things *better* to give me expected results?

I referenced the thread because this is currently broken because
of this one issue.

Would it be okay to put links on the website for not-prefered,
but GNU and FSF endorsed hardware, like having an FAQ to explain
what linux-libre implies and how to get working hardware (list
hnode and a number of sellers there), something like this?

I would refer to gentoo wiki section handbook, subsection
formating the disks (or smth like that) for this as it's very
understandable for inexperienced user in my opinion.
But that's just me, where I already had 14+ years of experience
when I read it 1 or 2 years ago. Gentoo documentation is overall
very good (the wiki section) and gets the balance right.

I think something similar to this is a nice approach.
Documentation is something most people don't do good
enough, and as long as the upstream docs aren't good, it would be
good to have something in one place to refer to.

But after reading this response of Esteban I agree with it more
than with what I have written. Maybe the best way would be to
provide temporary workaround to the documentation situation and
also encourage users to help us with changing upstream
documentation, so we can provide links to good, readable,
understandable manual sections from an inexperienced users
view. Maybe this could also be pointed out on the website / the manual.

Out of Guix suppport scope, but I have a mainboard (not with nouveau)
which showed problems with a certain 4.x version of Linux[1]. The debug
sugesstion by Intel is to configure and run the drm-tip branch[0] of
the kernel. I can't advocate how to package or do this here (which is
too bad), but for all things graphics related this will be suggested
by upstream most certainly.

You will be able to build a live-cd from an existing system with the
guix provided tools. Let's say you pick a GNOME-based system as the
configuration you build your system from, then you can build a
(limited) Live CD from that. I've identified a number of limitations
over the years, but for simple usecases the resulting system would
work.

Another option you have right nowm is to download the image (could even
be the qemu image) and install one of the system configurations that
come with it into a virtual machine like qemu.

Our general .iso can be written to a flash disk with 'dd' or even
burned to a CD/DVD (a feature that was introduced some time in the
last 12 months).

Not trying to derail this thread too much, but could you explain that a

This is moving beyond the current change with modular guix (which still
drops a bunch of modules into the store and compiles them), correct?

Linux drm-tip. I didn't link to it for reasons, but "git kernel.org linux 
drm-tip"
should help.. if it helps in your case at all. I'm not sure.

As far as my experience with other Operating Systems goes:
we need to make the keyboard layout configurable in the initrd.
You can already achieve this with a custom initrd today, but
having a service would be more convenient.
For expected defaults we should make this hypothetical service
default to en-us.
I see two possible entry points to writing the service here:

1) extending the console-keymap-service
2) writing a new service that extends the initrd and reuses code from
   the previously mentioned service.

Logical mistake can happen, I've constructed this from memory.

It could take some time. I need to extract those which are suited for Guix.
There's also "issues" I still need to think about more in depth, occasionally
I have (offline) discussions with people about this. For example:
There are operating systems which support booting multiple architectures from
one Live USB, to my knowledge only compatible architectures. The last discussion
happened so long ago that I need to gather sources for that (example OS'?).

The coreboot systems I have, and the small amount of the libreboot systems,

If I remember correctly NM had something about PAM and groups so that you

Gentoo has a neat little tool in their install image.

This is to reduce fingerprinting. With Guix it's even more crucial because
the user base is (probably) rather small. Compare to what you can find about
Torbrowser's reasons for displaying the same string.

They are meant to be included in the base of the installer image of Gentoo.
Gentoo's default license is GPL2, so I assume they will be licensed in
the context of the image's license.

For reference: https://packages.gentoo.org/packages/app-misc/livecd-tools
where they use the default Gentoo license (GPL2). You interact with this
usually with portage, so you will see the license statement then.
iirc the license file is then included on the system which builds the
ebuild through the definition of the license in the package definition.

Guix maybe, for a developer system you run out of RAM for everything
that has serious demands in RAM and/or Diskspace for building.

If waste of writes is your concern, getting a separate disk for
/tmp is a good choice. As long as you don't have to build big
applications from source/without substitutes tmpfs is alright.

Been there, tried that and considered it now only for machines that
will never build anything big.

That is because loadkeys is for the tty. In X you would use setxkbmap
or your WM/DM provided tools for setting it. setxkbmap comes as part
of the package 'setxkbmap' in guix.

For SDDM and SLIM the fact that it's just en_US is a bug in our

I'm on an older(?) guix version but the same fish version.

Integration of shells other than Bash are suboptimal in GuixSD at the moment,
you might want to search through the bugtracker and read the tickets I
opened a while back with regards to fish:

In this case you have to use patchelf, and use the conventional Unix
tools to figure out what's missing in rpath and interpreter.

As far as I can guess.

From what I've learned in the last couple of hours, the last problem could
be due to leftovers in your raco / dotRacket folder from an older installation.

As far as I know we don't even have a functional LXDE stack?
I've been working slowly on lxde + lxqt, none of them in a
state where you can log into it.

Nevermind my last email, I got a bit mixed up between lxqt and lxde.
(Oops, I even added 'lxde' myself)

 lxde is already a package containing all of the
 other lx* lxde* packages (+ pcmanfm etc) you list
 below and above. If there is something I forgot
 to include in lxde, which is already present in
 the lxde module, that's a bug. Otherwise, you can
 reduce this list already.

 is there a reason why you put icecat in a system
 profile instead of a user profile? Usually it is
 better to have this in your user profile, unless
 you want to have all system users to have access
 to it (instead of installation per user).

I think KDE and GNOME appear (but you won't be able to use them iirc
since you don't have them) because LXDE in theory can be used with
other DMs. I never tested this capability in GuixSD and doubt that it
will work since I only cared about LXDE alone when I packaged
this. Just regard it as a sideeffect which should eventually get
fixed. If it bothers you too much, report a bug about it.

If you want to know why this happens: SLIM (or whatever login manager
you use) detects any .desktop file in a certain location. LXDE
provides these .desktop files.
