Thanks Florian. After looking at the sys call documentation, i can see 
that it passes an argument to the kernel_restart function if I use 
LINUX_REBOOT_CMD_RESTART2 as the cmd. However as you mentioned the 
coreutils reboot or busybox's reboot do not support these options so I 
will write a shell script to wrap the system call.
