Make a kernel and fs build with upcoming jessie

During VM boot, the following message is printed:

Netkit kernel r1 (3.2.54), filesystem F7.0-r1

At the present time, scripts at startup are doing a lot of mounts and checks not very useful for netkit. Furthermore, it increases memory footprint and take time at startup. An idea could be to get rid of these scripts at startup and rewrite a unique script which simply mount the fs.

I am using your release. I found a possible problem. It is a know
problem, look here:
https://answers.launchpad.net/marionnet/+question/148329

I modified a lot the netkit filesystem, mounting it with the -W
option. My virtual machines got extermely slow. This you enable in
the netkit kernel this option:

CONFIG_BLK_DEV_UBD_SYNC

It should fix the problem:

I cannot check myself because the file /proc/config.gz is not
existent. I suggest to enable that too.

1. Here us my setup
   Debian

---

VirtualBox

Mac
2) I downloaded your code and built the core, kernel, and file system for netkit-ng
(In the end, I made no modifications to filesystem-tweaks)
3) Download the "Simple announcement" lab from the Interdomain routing section of
http://wiki.netkit.org/index.php/Labs_Official

4. For some reason, the original netkit setup (on routers) has symbolic links
   /etc/init.d/zebra --> /etc/init.d/quagga (this quagga script is installed with package quagga)
   /etc/zebra --> /etc/quagga
   So I make appropriate changes to the lab. For router1, for example, the line
   /etc/init.d/zebra start
   is changed to
   /etc/init.d/quagga start
   and the directory
   router1/etc/zebra
   is renamed to
   router1/etc/quagga
5. use lstart to start the lab.
6. on router 1 we see that the zebra daemon is not running. The phase 2 init script produces the
   error
   zebravty_read_config : failed to open configuration file /etc/quagga/zebra.conf : Permission
   denied

Comments: this lab does not in fact have a zebra.conf file, and it should be OK without it. But when > I do put one in /etc/quagga I still get this error.

see issue #3 : reducing memory consumption

At the present time not all packages have been included in the first release, as some packages are disabled:
