reboot ¶The reboot command is a convenience client program to instruct
the Shepherd (when used as an init system) to stop all running services and
reboot the system. It has the following synopsis:
reboot [option...]
It is equivalent to running herd stop shepherd. The
reboot command understands the following option:
Send commands to the socket special file file. If this option is not specified, localstatedir/run/shepherd/socket is taken.
Reboot the system using Linux’s kexec (this is equivalent to running
herd kexec root). The kernel that was previously loaded using
the kexec -l file command is executed directly instead
of rebooting into the BIOS, keeping the downtime to a minimum. See the
kexec command
documentation for more information.
This feature is only available on Linux-based systems. It has no effect
on systems where kexec is unsupported or when no system was loaded for
eventual kexec reboot. Last, if kexec reboot fails at run time,
shepherd falls back to normal reboot.
