Wow. If this is true than systemd has a bug here. The only reason kexec -e is called the distribution shutdown scripts is because the patch to /sbin/reboot never made it into sysvinit. All kexec -e really does is a single system call.

Systemd has incorrect hard coded paths to avoid a single system call???

Wow.

"kexec -e" does more than a single syscall. It also downs all network interfaces, shaper devices first.

Is it really just a single system call? afaics it does all kinds of stuff like uploading a kernel. Not sure I want to get into the business of doing that.
