Description Yosef Meller 2005-02-08 10:33:05 UTC

The superuser on a linux system doesn't have to be called root, it only needs to be the zeroth user. But /etc/profile checks the name rather than the number.

Reproducible: Always
Steps to Reproduce:
1. Change user 0 name to 'gever' in /etc/passwd
2. Update /etc/shadow to match.
3. login as 'gever'

Actual Results:  
The result is immediately visible - the prompt is green instead of red.

Expected Results:  
Test for UID instead of name
