Bug#797108: init-system-helpers: deb-systemd-helper doesn't remove old links when changing WantedBy= at package upgrade

[Louis Bouchard]

Hello,

I have tested the patch proposed in this bug and it doesn't work for me.

It does indeed remove the old WantedBy= link, but doesn't create the new one and
the two lines (old & new) remain in the dsh_state file.

Without the patch, the two lines are present in the dsh_state file, but the
second one is never created since in enable() :

>         my $create_links = 0;
>         if (debian_installed($scriptname)) {
>             $create_links = 1 unless no_link_installed($scriptname, $service_path);

no_link_installed() will return false for the second entry in the dsh_state
file, which is the link to be created for the modified WantedBy=

HTH,

Kind regards,

...Louis
