I build my own from debian wheezy by multistraphttps://github.com/topikachu/python-ev3 ... ild-rootfs
udev doesn't work with old kernel. But it can be fixed with the accept4 patch.
Also, the new bluez 4.99 changes a lot . I haven't find a way to setup the bluetooth nap. It not always work.
Others are OK. I even can use apt-get to install new application on EV3.
