@yann Thanks for the fast reply

Ok, I am opening a ticket, and providing a simple support script.

@olivierlambert I tried it in Debian 12.8/stable with sysvinit as init (and not systemd).

The package was installed without problem, but the agent is not started.

When run manually via sudo /usr/sbin/xen-guest-agent, the agent is then correctly detected by the dom0.

So it means no dependencies on systemd (which is good :), and only an init script in /etc/init.d/ is required for having full support.
