Your OS possibly does not support setuid shell scripts.
Create a script as above. Then set the owner to root and the permissions to 4555. Then, run the script as a normal user and run 'whoami'. If the output is root, then you have setuid shell script support on your system. If not, then you will have to 'encapsulate' the script inside a C program that can then be setuid root and not writable by anyone (for security).

chroot
CHROOT(8) BSD System Manager's Manual CHROOT(8)NAME
chroot -- change root directory
SYNOPSIS
chroot [-u -user] [-g -group] [-G -group,group,...] newroot [command]
DESCRIPTION
The chroot command changes its root directory to the supplied directory newroot and exec's command, if supplied, or an interactive copy of
your shell.
If the -u, -g or -G options are given, the user, group and group list of the process are set to these values after the chroot has taken
place. See setgid(2), setgroups(2), setuid(2), getgrnam(3) and getpwnam(3).
Note, command or the shell are run as your real-user-id.
ENVIRONMENT
The following environment variable is referenced by chroot:
SHELL If set, the string specified by SHELL is interpreted as the name of the shell to exec. If the variable SHELL is not set, /bin/sh is
used.
SEE ALSO chdir(2), chroot(2), environ(7)HISTORY
The chroot utility first appeared in 4.4BSD.
SECURITY CONSIDERATIONS
chroot should never be installed setuid root, as it would then be possible to exploit the program to gain root privileges.
