Disable keyboxd system-wide?

[Conrad Hoffmann]

Hi all,

I am encountering a weird issue with keyboxd. It only happens in 
combination with fakeroot and systemd, so I am not sure what to blame it 
on. But as temporary workaround, I would be interested if there is a way 
to disable keyboxd system-wide (as opposed to ~/.gnupg/common.conf), so 
unsuspecting new users do not run into this?

Thanks a lot,
Conrad
