Getting back to this, I face also issues that seems to be related with how systemd handles squid. 

Frequently when I try restart the VM the VM is stuch at stopping squid and it never restarts. 

 

Checking the differences between the autogenerated service file and the one shipped with squid I see: 

 

diff /run/systemd/generator.late/squid.service squid3-3.5.23/tools/systemd/squid.service

So do I just overwrite the  squid.service of the system with the one shipped with squid?

 

Thanx, 

Alex

systemd cannot cope with daemons like Squid-3. All you can do for now is
ensure that you use the init.d scripts to manage Squid. Do not use the
"service ..." commands provided by systemd.

Squid-4 packages that resolve these issues are in Debian experimental
awaiting an official upstream stable release.
 NP: the major bugs preventing upstream stable are not affecting the
Debian package features. You can use the Squid-4 package now if you wish
by adding that "experimental" repository to your apt sources.list,
update apt, then install/upgrade Squid with "apt-get -t experimental
install squid".
