sidu-base was a accident - we have not much packages with dependencies to a special init in installed systems. And our build scripts at the moment rely heavy on sysvinit - but that are run once scripts and will be mostly removed after the iso-build is done.
a few other scripts depend on sysvinit in the live iso - but as far as we can see run ok with systemd - but they will be changed. So the switch to systemd was not a big deal for us.
The decision to run with systemd in the future was short and hard: We had the choice to drop our gnome flavour or sysvinit. After a few intensive tests we decided do let sysvinit go
- Thats all.
