Yes, I have suggested this, it has been rejected by others saying that
we should ntp at boot to make sure th edate is correct for files being
setup etc. (most times dates are wrong, its slow, so bringing the date
forward is not a problem, the only ever issue is putting dates back,
which causes some 'too new' errors, i think the odd case this might
happen is not worth making the boot time of half of ubuntus users 30s
longer worth it)

Personally, I see NTP sit therre for 30-60 seconds far too often and I
think that is totally unacceptable.

DHCP is another culprit, we really need some kind of dependancy thing so
that gdm etc can start while DHCP is still starting.

But yeh, NTP is a killer and lots of people i know personally complain
about it
