Was well over 220 packages held back or wouldn't
install/upgrade.  I didn't keep a list as most
installed after I removed some stuff.  The stuff I had
to remove were ktorrent, dovecot and apache/myphpmoney
(none of which I was using).

I can't tell due to that graphical startup screen. 
The graphical startup screen gets to "initializing
root file system" before dumping me to the char mode
screen.  I tried different tty screens to see the char
mode from the beginning, but not successful.

How can I install this if I can't start the system. 
Well, not quite, I can boot from an old kernel, 2.6.8.
 Should I try to boot with that?  X won't work with
that, but I assume I can do an apt-get or a dpkg.

Re-install grub?  I think init is installed with
linux-image, right?

Is that a package name or just shorthand for the base
system?

Sorry I asked about how before reading the whole
thing. :-(

Thanks, Sean.
