You made Grml for people to be flexible in remastering it? I think Grml was, and is complete as it is. If I want to add a daemon at startup I need no systemd to successful remastering Grml. But of course it is your decision.
If you're interested in a Grml flavor *without* systemd you're invited to work on that, you might be also interested in picking up file-rc as upstream respectively package maintainer (file-rc being the init system we relied on so far and where no maintainer seems to be present anymore, esp. once both Alex and me will orphan it).
Thanks for the invitation to maintain Grml with sysvinit. But I will not have the time to maintain such a big change alone. But as grml is also listed in http://without-systemd.org/wiki/index.php/Main_Page#GNU.2FLinux_distribution... I send a copy of this post to the devuan mailing list. Maybe there will be someone who is using Grml and interested to keep this systemd free.

Systemd is the reason why I dropped GRML as an admin/recovery system, myself. or rather GRML dropped me, as the sytemd version fails on some of my older hardware. I mostly use a custom devuan image these days. Just my 2p. Cheers
