/*\
 * [Description]
 * This is a Phase I test for the reboot(2) system call.
 * It is intended to provide a limited exposure of the system call.
 *
 * [Algorithm]
 * 1) Two test cases for two flag values
 * 2) Execute system call
 * 3) Check return code, if system call failed (return=-1)
 * 4) Log the errno and Issue a FAIL message
 * 5) Otherwise, Issue a PASS message
 *
 * [Restrictions]
 * For lib4 and lib5 reboot(2) system call is implemented as
 * int reboot(int magic, int magic2, int flag, void *arg); This test case
 * is written for int reboot(int flag); which is implemented under glibc
 * Therefore this testcase may not work under libc4 and libc5 libraries.
