Hi Tim, thanks for the reply. I have not identified yet the problem to be solved.

If you refer that I use bash for root is the problem, there is no difference by switching root's shell to sh.

With sh as the shell for root:
1. Still cannot login as root from the console. Child process died error.

2. "su -l" doesn't work, child process died error.

3. su works. But the prompt is [\u at host name]#
Why it doesn't print root at host? whoami shows root.

What is the problem you think that I should fix? any ideas? any thread related error as the child process die when in root? 

Best regards
