I forgot to mention that this is on GuixSD, where ~/.config/guix/currend/bin is already in PATH, which maybe explains why I did not get a reminder. > In addition, be aware that Bash maintains a cache of commands it looked > up in $PATH. Thus it may be that, say, it had cached that =E2=80=98guix= =E2=80=99 is > really /run/current-system/profile/bin/guix.

I believe this is it. This also explains why =E2=80=98which guix=E2=80=99 = returned the updated guix while =E2=80=98guix --version=E2=80=99 claimed it was still th= e older version, which I found rather confusing. I am afraid being unaware of this has led me to inadvertently downgrade GuixSD whenever I reconfigured for the first time after a fresh install. Thanks! Diego
