Description of problem:

The following in /etc/profile fails in ksh, because EUID is non-existent.
"/etc/profile[17]: [: argument expected"

if [ $EUID = 0 ]; then
    # do something with the path
fi

In FC3, instead of $EUID was used: `id -u`

The package changelog says that 

* Sat Apr 16 2005 Bill Nottingham <notting@redhat.com> 2.5.41-1
- get rid of 'id' error messages if there is no /usr (#142707)

But replacing it with a bash-ism is no solution either ...

Version-Release number of selected component (if applicable):
setup-2.5.44-1

How reproducible:
Always

Steps to Reproduce:
1.Give a user ksh as login shell
2.Let him login
3.
  

Actual Results:  /etc/profile[17]: [: argument expected

Expected Results:  No errors during login.
