We wait for all operations, but we time them out. SysV start/stop
scripts are timed out after 5min which should be plenty time even for
the slowest scripts. You can freely increase (or even disable that) in
unit files.

first place before boot? What's that? in initrd?

If you want an executable started during boot, the easiest way is to
stick it some place (for example /usr/local/bin), and then place a unit
file like this in /etc/systemd/system/yourservice.service:

[Service]
ExecStart=/usr/local/bin/myservice

and then symlink this file to
/etc/systemd/system/multi-user.target.wants/yourservice.service to start
at boot.
