Hi Petter, hi Holger, please let us keep that for wheezy if really necessary. On Mi 04 Jan 2012 17:49:52 CET Holger Levsen wrote:

well, we did this is on purpose. IIRC to have to do changes in less places andalso to make upgrades easier.
The subnet change's reason was: GOsa² can only handle 8bit, 16bit and 24bit subnets. As 10.0.2.0/24 was considered to small, we expanded the subnet mask to what is commonly used with a 10.0.0.0 network -> that is 10.0.0.0/8.
The new and extended backbone network went from 10.0.2.0/23 to 10.0.0.0/8 earlier this year, but the server and gateway adressess where not moved from 10.0.2.0/23 to 10.0.0.0/8. I believe the gateway should change from 10.0.2.1 to 10.0.0.1. It might be a good idea to move tjener from 10.0.2.2 to 10.0.0.2 too, but that is not equally important.
Whereas the technical step is a tiny one (and probably unproblematic) I see quite an effort in documentation and infrastructure adaptions on upgrades. I work as sysadmin in loads of contexts and the first IP is mostly not the gateway here around... (sometimes it is x.y.z.254, x.y.z.253, x.y.z.z, ...).
Without this, a lot of third party packages will propose the wrong gateway address when configured to connect to the skolelinux backbone network.what packages do you have in mind? So far we didnt notice anything like this....
I have nothing here that fails on the current setup with Debian Edu squeeze. Not failures reported so far. Once DHCP, DNS, routing, etc. are configured correctly, applications work out of the box. What do you have in mind?
This change will require some testing,and changes to the documentation and translations too :(
Wheezy-wheezy-wheezy... ... (or I will introduce Samba4 from backports *g* )
As part of this fix, I plan to move the network configuration function from debian-edu-install to debian-edu-config, to get all the subnet related code in one package.
...I'm rather a lot against this change too. It's really not needed and has quite some potential of additional breakage. Could you imagine not doing this part of the change?
If there would be voting in Debian Edu I would also vote against that. I am not convinced that this change is necessary for squeeze and I am neither convinced that this change is needed for Debian Edu at all...
but only my 5¢...
