So from a security standpoint, if one must change the hostname, then one
must also create a new .Xauthority file? I see the .Xauthority file on my
machine (with the hostname that was changed) is not editable with a text
editor (also this is probably to be expected?).
If the hostname must be changed, then X (as in XFree86) must be re-installed
as a MacPort?
