Because reboot tries to initiate reboot, but gets EPERM.
(BTW, can you please upgrade to something newer than busybox-1.13.x?)

* Make a new user with uid 0 and login shell=/sbin/reboot.
* Use sudo mechanism to allow some users to run /sbin/reboot
* Make busybox binary setuid root, and change reboot applet from
_BB_SUID_DROP to _BB_SUID_MAYBE in this line:
IF_HALT(APPLET_ODDNAME(reboot, halt, _BB_DIR_SBIN, _BB_SUID_DROP, reboot))
(warning: this will allow any user to run reboot)

Works for me as long as busybox binary is setuid root:
$ busybox login
myhost login: _

Using su command.
