Package: init-system-helpers
Version: 1.69+nmu2
Severity: normal

Dear maintainer,

During a routine upgrade, I saw:

Setting up systemd (262-1)…
Unrecognized signal name "SIGRTMIN+25" at /usr/bin/deb-systemd-invoke line 179.

Indeed, deb-systemd-invoke has this around line 179:

    if ($action eq "daemon-reload") {
        $signal = 'SIGHUP';
    } else {
        $signal = 'SIGRTMIN+25';
    }

Not sure what to do about that, trusting you to know better.

Thanks for your work, regards.

Florent
