Re: Re： How can I add a user for openbmc and remove the default root user?

[Thomaiyar, Richard Marian]

Hi Gunnar,

Yes root user can't be deleted (basically uid 0), can't be deleted. The 
method works for other users only, like in case Liu, he wants to delete 
the newly created user.

Regards,

Richard
