We have a configuration for our embedded system which is working via

Not sure if this is ‘wise’ – if anyone has technological arguments

Just one. systemd is a bit larger. So it will increase the boot time if
your platform is I/O limited (many embedded systems are).
The good thing I noticed is that it shuts down a lot faster than
initscripts. (I don't understand why I can boot my system in 2 seconds,
but shutdown takes over 5 seconds...)
The 5+ seconds may be from sendsigs on shutdown or reboot:
echo "Sending all processes the TERM signal..."
killall5 -15
sleep 5
echo "Sending all processes the KILL signal..."
killall5 -9
OMG, indeed, this is utterly braindead!
An no one (except one of the systemd folks) has come up with a program that
just waits for the the processes to finish (with a timeout) and only uses the
"-9" double barrel shotgun to finish only the ones that didn't respond?
(though doing that is rather pointless if the system power is about to be cut
anyway...)
Kind regards,
