Hi Carsten,
I did it slightly differently (without redoing the NFS root):(1) copy grml kernel and aufs modules package to nfsroot (2) bind mount /proc into nfsroot (3) chroot into nfsroot
this is not a smart way to maintain your FAI setup. Fiddling with the nfsroot in a way not documented in /etc/fai is just asking for trouble a year or two later on. That's why I documented the proper way to do this in the Wiki...
Regards, Michael
