4.4.1 kernel fails to generate initrd.img to /boot on this system [SOLVED]

[thunderrd]

It's been about a month since last d-u, and I get this result, failing to install the new kernel:

I'm not sure what to do here, I tried deleting the dead links, and running the d-u again, with the same result.

Yeah, I got some help on IRC.  I missed the bit about busybox in the output but can't understand where busybox went; it's very weird for it to have gone away.  I mean, it's part of the base system, and certainly I did not remove it manually, so something caused its demise.

Anyhow, thanks for the answers, it's solved.
