Re: Guix does not understand config.scm

[Thomas Sigurdsen]

Hi,

I've figured some things out here, hope you can use it. For the future, I
find it much easier to test and help if you attach the file or post it to a
pastebin (see the wgetpaste program to make that easier). Of course you
remove whatever is of a security or privacy concern for you.

I don't know what the 2 servces I've commented out where supposed to do. I
think you should look up defining services in the docs, or maybe you wanted
something else entirely.

Debugging line by line is not simple, or something I do. But I use strace. If
I get unintelligible errors from guix I usually do:
strace -o /tmp/strace.out -T -s 2000  -f guix-command
Then use less or grep or some other tool to inspect the output
in /tmp/strace.out. Things to look for are error, warning and anything it
says about files not part of guix, i.e. files in your home directory (not
including ~/.config/guix/latest and similar) or wherever you keep your guix
personal files (configs modules and whatnot).

I also look at other peoples configurations. There are quite a few online in
github and notabug and similar that will give you a good idea of how to do
things. Mine is here: https://notabug.org/thomassgn/guixsd-configuration/

And last but not least, have a git clone of the guix sources from savannah
and check the tests (gnu/tests/) and examples (gnu/system/examples).

You can also read the source, but by this time I've gone to IRC or something.

> 2. Where can I find the full list of modules for "use-modules"?

It will say in the info documentation. Or look through the sources.

Also, run 'visudo --check --file=/etc/sudoers' when you change it, cause
last I bodged it, guix had no idea the sudoers file was not working. One of
the few bad accidents I've had with guix where guix couldn't fix guix
because the problem was not guix.

And you might want to have sudoers somewhere else so you can build your
system without root. You still need root to "install" (i.e. reconfigure or
similar) your system.

Hope this helps.
