I do not set and it is there by default.
I've take a look at coreutils's src/Makefile.am
and found that: ls and dir are made by linking all the (same) object files(.o)
That's why they have same filesize but different md5sum.
But, should dir be a symlink or an alias to ls?
[vuhung@ src]$ md5sum /usr/bin/dir /bin/ls
84db07f1ad799515bce09f75a7f169d7 /usr/bin/dir
81ffaed1155462cca52465f07d778afb /bin/ls
[vuhung@ src]$ ls -l /usr/bin/dir /bin/ls
-rwxr-xr-x 1 root root 81240 Nov 18 2007 /bin/ls
-rwxr-xr-x 1 root root 81240 Nov 18 2007 /usr/bin/dir
[vuhung@ src]$ cat /etc/redhat-release
CentOS release 4.6 (Final)
[vuhung@ src]$ rpm -qf /usr/bin/dir
coreutils-5.2.1-31.7
[vuhung@ src]$ rpm -qf /bin/ls
