Re: xenconsoled defunct after xl create on fresh debian 12

[Volker Weber <volker@xxxxxxxxxxxxxxxxxx>]

Hi,

yes, systemd uses the init.d xen scripts, but the PIDs in the files are 
correct:
$ systemctl status xen

I can't find any xen 4.17.3 packages in debian bookworm, from which 
repro did you get them?
