fai-cd fails

[Michael Schneider]

Hi

I’m trying to build an offline CD with the command fai-cd that installs Ubuntu 16.04. For the installation I use a Debian Stretch nfsroot.

1) ./mk-basefile -J XENIAL64
2) fai-make-nfsroot -C /srv/fai/etc -v
3) fai-mirror -b -C /srv/fai/etc-ubuntu -v -m1 -cFAIBASE,SWISS-GERMAN,GRUB_PC,UBUNTU,XENIAL64,XENIAL /srv/mirror
4) fai-cd -g /srv/fai/etc-ubuntu/grub.cfg  -f -Jm /srv/mirror ubuntu1604.iso

The 4th command fails as follows:
Copying the nfsroot to CD image
Copying the config space to CD image
Copying mirror to CD image

Does anyone have a hint for me?

Thanks,
