Strange. OK, my mail server hasn't yet SPF or DKIM, which might raise
the mail's spam score, but just silently dropping the mail seems
pretty uncivilised (but hey, it's Google, so...)
Perhaps now that you mailed me, gmail is a bit friendlier.

No problem, formatting is fine.

Glad we found it :-)

Install apt-file: very recommended. It lets you search for Debian
packages containing a file (by file name, even when the package
isn't installed):
| tomas@trotzki:~$ apt-file search systemd-ask-password
| manpages-de: /usr/share/man/de/man8/systemd-ask-password-console.service.8.gz
| manpages-zh: /usr/share/man/zh_CN/man1/systemd-ask-password.1.gz
| manpages-zh: /usr/share/man/zh_TW/man1/systemd-ask-password.1.gz
| plymouth: /lib/systemd/system/systemd-ask-password-plymouth.path
| plymouth: /lib/systemd/system/systemd-ask-password-plymouth.service
| systemd: /bin/systemd-ask-password
| systemd: /lib/systemd/system/multi-user.target.wants/systemd-ask-password-wall.path
| systemd: /lib/systemd/system/sysinit.target.wants/systemd-ask-password-console.path
| systemd: /lib/systemd/system/systemd-ask-password-console.path
| systemd: /lib/systemd/system/systemd-ask-password-console.service
| systemd: /lib/systemd/system/systemd-ask-password-wall.path
| systemd: /lib/systemd/system/systemd-ask-password-wall.service
| systemd: /usr/share/man/man1/systemd-ask-password.1.gz
| systemd: /usr/share/man/man8/systemd-ask-password-console.path.8.gz
| systemd: /usr/share/man/man8/systemd-ask-password-console.service.8.gz
| systemd: /usr/share/man/man8/systemd-ask-password-wall.path.8.gz
| systemd: /usr/share/man/man8/systemd-ask-password-wall.service.8.gz
so now we know systemd-ask-password lives in /bin and comes with package
systemd. But I guess you are looking for its config file, perhaps something
in the whereabouts of /lib/systemd/system/systemd-ask-password-console.service.
Note that the usual way of customizing that is not by changing the
service file in /lib/systemd/... but to put a new service file somewhere
in /etc (/etc/systemd?) overriding it. My wisdom there is pretty
sparse, perhaps some systemd buff can chime in here.
Cheers
