But don't you apply updates? I believe that's what Ralf meant. 12.04
still receives security fixes, which you really don't want to leave out.

If you purge the grub package, and your system is set to install
recommended dependencies, it might install grub again when you update
the kernel - that's what Ralf was saying.

One way to avoid this is to install a dummy package, another way is to
place a hold on the packages after purging them - that will prevent them
from being reinstalled. Do something like this:

1. 'dpkg -l | grep grub'
 This lists all the installed grub packages
2. 'apt-get purge <list of packages from above step>'
 This removes them
3. 'apt-mark hold <list of removed packages>'
 This prevents them from being installed again

Don't send mails to us off-list, as we see your replies to the list
just a few minutes later. If your mailer has a Reply To List option,
just use that. Otherwise just reply to the list address.

That sounds like a good idea if this is a production system, although
it should have no effect if you boot via PXE.
