And for a bit more information.. vconfig (vlan package) is kinda obsolete these days, iproute package took its role and extended functionality to match current kernels. What I'm trying to say is that it's probably a good idea to use more appropriate tools to start with, if the talk is not about compatibility with some old code. Busybox has iproute built-in, but its functionality is not sufficient for configuring vlan interfaces (not even 1.18). I'll take a look into this. /mjt -- To UNSUBSCRIBE, email to debian-boot-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?

I think we might miss > the vlan modules (8021q garp stp) in d-i for that. That was my first thought as well. But then I tried on a squeeze desktop, where iproute had no difficulty adding the tagged interface, but busybox still failed (although it could delete it beforehand). -- Cheers, Feri. -- To UNSUBSCRIBE, email to debian-boot-requ...@lists.debian.org with a subject of "unsubscribe".

Are you sure the vlan kernel modules are loaded? I think we might miss the vlan modules (8021q garp stp) in d-i for that.

I wonder if you really need this after all. vconfig is deprecated, and even the current squueze RC1 busybox seems to understand # ip link add link eth0 name vlan10 type vlan id 10 although the operation itself fails.

Just for the record, the difference between the size of the binary in busybox-udeb 1.17.1-9 (as is currently in git) when built on i386 with and without vconfig is 384 bytes. vconfig in is 212732, vconfig out is 212348. I built both locally in the same chroot to remove any other biases (gcc version, etc). Given that I am planning on putting vlan support into wheezy, if someone wanted to make an appropriate commit... - Matt -- To UNSUBSCRIBE, email to debian-boot-requ...@lists.debian.org with a subject of "unsubscribe".
