linux-headers-3.2.0-105 not in precise-security

Hi,

I noticed that linux-headers-3.2.0-105 is not in precise-security.

> Package not available
http://packages.ubuntu.com/precise/devel/linux-headers-3.2.0-105-generic

Looks like it was published but then removed again: https://launchpad.net/ubuntu/precise/amd64/linux-headers-3.2.0-105-generic

My question is why was it removed? Are the headers not always in the security repo if the image is? http://packages.ubuntu.com/precise/linux-image-3.2.0-105-generic

For previous generic kernels like 3.2.0-102 and 3.2.0-104 the headers are also in precise-security instead of only precise-update.

See http://packages.ubuntu.com/precise/linux-headers-3.2.0-102-generic and http://packages.ubuntu.com/precise/linux-headers-3.2.0-104-generic

I ran into this trying to install the virtualbox guest additions into a precise64 Vagrant with a 3.2.0-105 kernel. The guest plugin tries to install the latest headers like 'linux-headers-`uname -r`'

see https://github.com/dotless-de/vagrant-vbguest/blob/d36ba2e4ae00577b4169bf1336a6a3264277c1e7/lib/vagrant-vbguest/installers/debian.rb#L31

this fails because in the box I am using next to our own repo only precise-security is in the sources.list. I feel like adding precise-update to the sources.list in the box will have too much side-effects and adding this linux-headers .deb to our own repo for just this kernel also seems like a bad idea.
