Upgrade error in nfsroot

Hello,

when upgrading FAI inside the nfsroot with 'fai-make-nfsroot -v -k -N', I got:

Preparing to unpack .../15-fai-nfsroot_5.9.2_all.deb ...
dpkg-divert: error: 'diversion of /etc/init.d/rcS to /etc/init.d/rcS.orig by fai-nfsroot' clashes with 'diversion of /etc/init.d/rcS to /etc/init.d/rcS.distrib by fai-nfsroot'
dpkg: error processing archive /tmp/apt-dpkg-install-hXzBfK/15-fai-nfsroot_5.9.2_all.deb (--unpack):
 new fai-nfsroot package pre-installation script subprocess returned error exit status 2

when upgrading FAI from 5.9.1 to 5.9.2

I had to manually chroot to the nfsroot and remove the diversion, then it worked. Maybe this should be included in the preinst script.

Bye,

Andreas
