This is only true to some extent. The local guix command still relies

on things in the system, such as the guix daemon itself, so you ought

to keep it up to date.

GUILE_LOAD_PATH does not point to the system cache "instead of" the

user cache, it gets expanded via profiles as everything else. Since

Guix has a system-wide installation of guile-3.0-latest, the guile

paths get set. You should probably install Guile locally instead of

system-wide if you plan on having the two diverge farther.

No.  The Guix command as built by `guix pull' sets its own load path,
but respects system paths too.  You can check by spawning a REPL:

scheme@(guix-user)> %load-path
$1 = ("/gnu/store/yi47s6iy3glwzimy3nch1h7c9hjzmyw8-guix-module-
union/share/guile/site/3.0"

For the record, guile has been a part of the system profile since
%base-packages were first defined, so if your load paths break, there
is probably a larger issue at hand.  In this particular case, your
local guix profile ought to shadow anything that's in /run/current-
system, so I don't really get how the ABI match is triggered.  Perhaps
you might want to debug that in a REPL.

Cheers

Maybe the system guix has a package module that does not exist in the
user guix, so guix tries to load the system package module instead of
the non-existing user package module?

Greetings,
Maxime

But are there any good reasons to respect $GUILE_LOAD{,_COMPILE}_PATH
at all? Usually, we use wrap-program etc. to set load paths (guile,
python, PATH or otherwise). Maybe guile-launcher can be modified to set
the load path instead of appending to it?

Greetings,
Maxime.

IIUC the guix command does not particularly need to provide support for
multiple profiles, so we could isolate it.  After all, extensions ought
to be installed in the user's (single) current-guix profile, no? 
(Disregarding the use of guix environment/guix shell, of course.)  Or
more accurately, GUIX_EXTENSIONS_PATH serves as a different escape
hatch.

In my system.scm (I attached it) I do have a package (fdm-git) that

doesn't exist elsewhere (because I need a patch that is upstream but

not in an fdm release yet).

Right now I can't test without fdm-git because when doing guix

system reconfigure, it tries to build guix but its tests fails. I'll

bugreport about that.

Denis.

The only relevant package from your system.scm (in the context of this

problem) would be the guix package, but you're not even editing the

guix service so it'd be a file removed from guix upstream since you

last reconfigured.
