Debootstrap works just fine. I use that exact procedure to create
ubuntu images all the time. Note that you probably want
something
larger than a 750 MB filesystem, as a large Ubuntu install can
grow to
be a couple GB over several years.
Also, you will need to edit several things in the resulting etc
directory before the filesystem will boot properly. You need to
create
a tty0 in event.d (copy over and modify from tty1), you need to
add tty0
to securetty, and you need to modify network/interfaces to be
appropriate for your setup. Note that recent versions of ubuntu
try to
be smart about MAC addresses, which will cause problems if you
don't
pass a constant MAC address on the command line. If the MAC
address
does change, you will probably need to go into
etc/udev/rules.d/70-persistent-net.rules and clean out the old
interfaces, or you will find that eth0 is no longer active.
