Good point. It did not occur to me to try asking the Ubuntu howto author. Often such person may have moved on and has forgotten how he/she did it, or his/her experience may be limited to a specific successfull installation. It is also very personal to ask someone for advice. It seems safer to ask a pool of users who are active members and are likely to have current knowledge. > The message is being received, processed and delivered.
