This patch ensures that always the current profile's daemon will be used.
The .service file contains the path to the guix-daemon within the store. Thus
when copying the file, it will point to the very version of guix-daemon used
at the time of copying – even after system upgrade or when this version has
been garbage collected from the store.
* doc/guix.texi (Binary Installation): Change example code for installing
the systemd and Upstart files to use symbolic links instead of copying
the files.
