Hi there,
While experimenting with Guix and installing one more package the disk of the test system filled to 100%. After shutting down the system to provide more disk to the VM, after reboot, the gdm session is indefinitely started and killed.
I tried to boot into non-x11 (level3) or single user mode but unfortunately the option I pass to Grub seems not to be recognized by the linux-libre kernel. Any hint where I find the correct boot options for a Guix System, so I can repair my system?
Thanks,
Alex
PS: one more thing. Is there any documentation about the packages? How to use them after just Guix install? After installing a package, e.g. a window manager like exam or a desktop environment like lxde additional steps are necessary for a user to use them. Can I find these steps somewhere? In particular to do the configuration such that it is compatible with the package and will not brake after updating the package to a new version.

Hullo Alexander,
[It's just ‘Guix’, by the way.]

Which option did you try? I've happily purged all memory of which
obsolete System V run-level did which obsolete thing (and Guix
probably should, too).

The kernel doesn't play a role here. It's the (early) user space
that looks at the kernel's command line, and performs certain
actions when it sees (a) particular magic keyword(s).

I think the only ones are currenly ‘--load’, ‘--root’, and
‘--repl’. The latter allows for some very rudimentary debugging
and fixing but it's not exactly pleasant.
In keeping with Guix's idiosyncratic syntax, one could add
‘--rescue’ and corresponding menu entry to only mount the root
filesystem and spawn the current system's bash shell. What do
people think?
Soon, we'll have to add ‘--help’…
Kind regards,

Hi,
I tried “single” and 3. Now I tried —root and it still booted into gdm.

Thanks! ‘single’ *might* be worth supporting as an alias,
although the preferred way to expose this would be a GRUB menu
entry and the argument wouldn't matter.
> Now I tried —root and it still booted into gdm.
I don't see why it wouldn't. ‘--root <file name>’ specifies the
root device.
Kind regards,

Aha, nope, sorry.

Yep. It's a Scheme REPL that also has a *very* rough ‘,bournish’
mode, but it's (ironically) not very useful with Guix because it
lacks
tab-completion (fun with store hashes!) and any useful
line-editing or
history (so if you make a typo you can type the whole thing anew).
That's true for the Scheme mode, too.
Believe me, I am not defending the status quo of Guix rescue
modes.
Your current best option is booting a live medium like the Guix
installer to free up some space and reboot.
Kind regards,
T G-R
