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,

T G-R
