Ask user for old service file

[Pitillo]

As discussed here I've added questions to the postinst file to ask the user whether he wants to keep the service file under /etc/systemd/system/evcc.service and the binary under /usr/local/bin/evcc

For now I didn't have time to test this. If anyone can do so, feel free.

Sieht Klasse aus, bräuchte aber noch den erwähnten Test. Kann ich unter OSX leider nicht machen :/

Ich habe mir jetzt heute die Zeit genommen und das ganze Mal getestet. Ein paar kleine Bugs waren drin. Hier der Output des Tests:

root@JHPC:~/projects/evcc# rm /etc/evcc-userchoices.sh
root@JHPC:~/projects/evcc# dpkg -i release/evcc_0.89.0_amd64.deb
(Reading database ... 41569 files and directories currently installed.)

Unpacking evcc (0.89.0) over (0.89.0) ...
Setting up evcc (0.89.0) ...
An alternate service file was detected under '/etc/systemd/system/evcc.service'.
This is probably due to a previous manual installation.
You probably want to delete this file now. Your evcc configuration stays untouched!
Shall '/etc/systemd/system/evcc.service' be deleted? [Y/n]:
y
The file will be deleted.

Ok. We will keep that file. Keep in mind that you may need to alter it if any changes are done upstream. Your answer is saved for the future.

Klasse- also rein damit?

Aus meiner Sicht schon, also habe es halt wie im Log zu sehen rudimentär mit 3 mal installieren ausprobiert und es scheint genau so zu funktionieren, wie ich es mir vorstellen würde :D

Top, vielen Dank!
