I installed Guix into my system, and I've been enjoying using it. However, I found that, after installing it, when I logged out and back in, and then started Emacs, Emacs could no longer see my system's info pages (including Emacs's own info pages). I found that the Emacs variable Info-directory-list only contained "/home/me/.config/guix/current/share/info", so it couldn't see the info pages in "/usr/local/share/info/" and "/usr/share/info/". According to the Info-directory-list docstring:
If nil, meaning not yet initialized, Info uses the environment variable INFOPATH to initialize it, or ‘Info-default-directory-list’ if there is no INFOPATH variable in the environment, or the concatenation of the two if INFOPATH ends with a ‘path-separator’. I found that INFOPATH is being set in /etc/profile.d/guix.sh, which does this: # Export INFOPATH so that the updated info pages can be found # and read by both /usr/bin/info and/or $GUIX_PROFILE/bin/info export INFOPATH="$_GUIX_PROFILE/share/info${INFOPATH:+:}$INFOPATH" Since it does not append a colon at the end, Emacs doesn't add the directories from Info-default-directory-list. I added a colon to the end and restarted Emacs, and it fixed the problem. So I'd suggest adding ":" to the end of INFOPATH in /etc/profile.d/guix.sh. Thanks.
