Dear Marc,
I think it is time now to supply systemd unit files to start apt-cacher, as
/usr/share/doc/systemd/NEWS.gz shows:
```
systemd System and Service Manager
CHANGES WITH 257:
...
Announcements of Future Feature Removals:
...
* Support for System V service scripts is deprecated and will be
removed in v258. Please make sure to update your software
*now* to include a native systemd unit file instead of a legacy
System V script to retain compatibility with future systemd releases.
...
```
That is with the next system (major) version v258 apt-cacher does not start any
more. Currently, we already have systemd v257 on testing.
Many thanks for maintaing apt-cacher, great job!
Chris
