+1 for the shebang but I think we want to keep this for people running:
sh install.sh, eg on Debian where sh is dash?

Hm.  Good point.  I'll restore it in a v4, but I'll give it some time

[bug#74962] [PATCH 3/3] etc/guix-install.sh: Fix quoting and other issues.

[Maxim Cournoyer]

This change fixes most issues reported by the 'shellcheck' command.

* etc/guix-install.sh (add_init_sys_require): Use -n instead of ! -z.
(sys_create_build_user): Quote variable expansion.
(sys_delete_build_user): Likewise.
(sys_create_shell_completion): Likewise.
(sys_delete_user_profiles): Likewise.
(main): Replace $@ with $* inside string.
