Note that with systemd and even with modern SysV init with insserv you can't (in general) pin-point the exact order of a script simply because they just form a tree, not a list. > After switching from SYS V boot to systemd boot, how can I achieve a > similar order, so that only very basic tasks (bringing network up, > mounting filesystems) are performed before my script runs and all the > remaining tasks are performed after my script was finished?

If you want to provide a native systemd unit, something like this sohuld be fairly equivalent: # equivalent of "run during early boot in rcS" DefaultDependencies=no After=remote-fs.target # run before most other services, i. e. still during early boot Before=basic.target You could also directly translate your original Before=console-screen.service kbd.service but I suppose you don't need to be that specific?
