I don't think so:

[root at halifax ~]# type su
su is hashed (/bin/su)

[root at halifax ~]# file /bin/su
/bin/su: setuid ELF 32-bit LSB shared object, Intel 80386, version 1
(SYSV), for GNU/Linux 2.6.9, stripped

[root at halifax ~]# type sudo
sudo is /usr/bin/sudo

[root at halifax ~]# file /usr/bin/sudo
/usr/bin/sudo: setuid ELF 32-bit LSB shared object, Intel 80386, version
1 (SYSV), for GNU/Linux 2.6.9, stripped

[root at halifax ~]# sum /bin/su
22494    24

[root at halifax ~]# sum /usr/bin/sudo
63311   138


Thanks,
	Uwe
