RE: RedHat user/group names ?

[Stephen Smoogen <smoogen lanl gov>]

Hello Mr Kern.

I think the problem is that useradd, etc are stopping email addresses
that can't be delivered to... sort of a common stop people from shooting
themselves in the foot. THere seems to be a need for a
'--shoot-me-in-the-foot' flag that allows this.
