Sir you are missing the point. Stop confusing the guy. What you're saying is
based upon an
assumption that this trick would be used whenever root logged in. Now why would
that be
necessary? If you log into xdm as root you won't *need* to futz with this stuff
because xdm
will have already set it up for you. The *only* reason he'd be doing this is
because he su'd
to root while logged in as another user. Note that I told him to do this
*after* he su'd to
root. In this case, .Xauthority will not be written to, only read. And, why the
hell would he
want to use ssh? He's doing this on the same frigging machine. He said he
logged in with xdm
right? Damn it I hate it when people spread disinformation like this.
