Hi, I have made a small change in fai-make-nfsroot to display the environment variable FAI_DEBOOTSTRAP_OPTS in the echo command which is issued before the actual call of debootstrap. I have made this modfication to our local installation and I think it makes sense to be included upstream as well since the output should also include any extra options to debootstrap which can make the latter fail in some cases.
Regards, Adrian
