right, however, in the absent of a fixed ipconfig, we should still add
this workaround as you propose, otherwise netboot would be in such cases
simply broken.

yes, live-config.
unrelated to that: currently, the initial network config (in non-netboot
situations) is done by live-boot-initramfs'es 23networking live-bottom
script. this at some point needs to go to live-config too. or in other
words: adding above hack is not that bad as most of the things in there
would be needed once 23networking is moved from live-boot to live-config
anyway.
patches for live-config more than welcome, i'm retiteling/reassign the
bug to live-config.
