     Actually I burn disks on my HP not on the Dell I carry to 
meetings.    I test them on my Dell to avoid rebooting on the HP. The
Dell when online at the meetings is exposed to the Internet.  I am 
behind a router here and my greatest fear is a
a mistake at the upstream repositories..  So far only one kernel was 
balky and when a parameter was removed
from the boot parameters it worked fine.
