> I noticed that the "alignment.sh" is not ran on my systemd images. I think I opened a bug about systemd ignoring ".sh" scripts but that was fixed and also not the main issue here. After looking at src/core/service.c of systemd the rcS.d is not looked at.

Hi Holger,

The proper way to integrate this into systemd is to create a unit file. What must be run before alignment.sh? what things depend on it?
Then depend on it from the proper targets. 

The workaround you suggest runs the risk of incorrect ordering as things migrate from SysV init.
