In todo.py (line 1003), anaconda takes the hostname that's
been looked up by resolving the address assigned by dhcp
(line 128), and makes it an alias for localhost.localdomain,
which makes sendmail rewrite outgoing mail headers to be
from <email@example.com>, which is bad.
It probably breaks various other things as well.
This issue has been assigned to a developer for further action.
