The contents of /etc/apt/ in the nfsroot should be solely determined by the
contents of /etc/fai/apt/ on your server, so you might want to check that.

I couldn't find any point where such a source.list file is created either. I'd
only see one possible point: Assuming that /etc/fai/apt/ has such a
sources.list.d layout as well on your site, the initial call to debootstrap for
building the nfsroot may leave behind that sources.list. If you could confirm
this behaviour, I'd opt for rather patching make-fai-nfsroot: It should clean
out /etc/apt in the nfsroot before copying /etc/fai/apt/. Thomas, would that
make sense?

Best,
Michael
