While not done by systemd, isn't is what is done on Debian when
kexec-tools is installed ?
It provides a 'coldreboot' script that does the following :
#!/bin/sh
NOKEXECFILE=/tmp/no-kexec-reboot
/bin/rm -f $NOKEXECFILE
touch $NOKEXECFILE
/sbin/reboot $*
FWIR, using reboot will quickly kexec into a new kernel.
Kind regards,
