[Users] Debian 7 HN Repository

[Johan Wilfer]

Hi again,

When we are talking about the new Debian repro this is the thread about 
my issues when installing a new HN. (Sent to the list 1,5 weeks ago).

Any thoughts on these findings?

I cc Ola and CoolCold as well, hope that's ok.

After upgrading now I see that the new kernel appear above so now I have:
#update-grub
Generating grub.cfg ...
Found linux image: /boot/vmlinuz-3.2.0-4-amd64
Found initrd image: /boot/initrd.img-3.2.0-4-amd64
Found linux image: /boot/vmlinuz-2.6.32-openvz-042stab081.5-amd64
Found initrd image: /boot/initrd.img-2.6.32-openvz-042stab081.5-amd64
Found linux image: /boot/vmlinuz-2.6.32-openvz-042stab081.3-amd64
Found initrd image: /boot/initrd.img-2.6.32-openvz-042stab081.3-amd64

That means GRUB_DEFAULT=2 doesn't need to be changed to 4 and so on on 
"apt-get upgrade". But it still needs to be changed the first time.
