I have seen in the /etc/profile file that it suggest you to do something like

source $GUIX_PROFILE/etc/profile.

This causes problems on systems where the startup file is executed by
a posix /bin/sh, as this is bash specific.

Any reason not to use

. $GUIX_PROFILE/etc/sh

instead in that hint?

(I noticed this on debian, .xsessionrc is using /bin/sh to interpret
this when starting up the x session, and that defaults to dash
on debian and derivatives.)
