In order to avoid manually updating the alias each time the package is
upgraded, you can use a declaration in guix home:
(home-environemnt
(services (list
(service home-bash-service-type
(home-bash-configuration (guix-defaults? #t)
(aliases `(("mscore4" . ,(file-append musescore
"/bin/mscore")))))))))
If you do not wish to use guix home, you could also use the extra-special-file
service in your system configuration:
(extra-special-file "/usr/bin/mscore4" (file-append musescore "/bin/mscore"))
Just make sure /usr/bin is in your $PATH.
