Hello,
in a %post I need the hostname of the machine being installed. hostname and
python's os.uname() report localhost.localdomain while anaconda displays the
hostname that comes from the DHCP server in the GUI. How do I get the value
which comes from DHCP? Is it stored somewhere or my only possibility is to parse
/etc/sysconfig/network ?

Thanks,
Alexander.
