problem with 2.6.6.

[Matthias Lechner]

hi!

i'm trying to start a debian-linux network in the lab i work for. after 
configuration of fai-2.6.5 i got to the "mountpoint redefined"-bug wich 
should be fixed in 2.6.6. so i "apt-got" version 2.6.6. and restartet 
make-fai-nfsroot, which aborted with the following error messages:

[...]
Creating base.tgz
,,/etc/fai/sources.list" -> ,,/usr/lib/fai/nfsroot/etc/apt/sources.list"

the strange thing: this only occurs with version 2.6.6. i downgraded to 2.6.5 
and it worked perfectly, so it can't be an external problem like a 
non-working DNS- or Debian-Server. i also tried an alternative server, 
recieving the same messages. 
do you have any ideas what to do?

thanks in advance
