~/.guix-profile cannot be pre-loaded like this as the relevant paths are
stored in ~/.guix-profile/etc/profile, which simply won't exist.
However, guix package will output a relevant hint that instructs the
user to reload the profile, so this isn't a problem.

This prevents Emacs from loading the autoload definitions found in its

installed) from blocking the script and asking the user to input the Scheme

If $XDG_DATA_DIRS is unset, default value of "/usr/local/share:/usr/share"
is used according to XDG Base Directory Specification. However,
/etc/profile.d/guix.sh treats this value as empty list when appending its
own directory, so after installing Guix on the system, launchers such
as Rofi stop searching for .desktop files in /usr/share/applications/
and can't launch applications other than those installed with Guix.

The 'task' means that events that led to this job starting will be blocked
