sysv-rc - overwrite /etc/init.d/rc

[Reto <blackhole1@gmx.net>]

Hi!

I installed Knoppix on HD. When I try to update using dselect, I always 
get an error while unpacking new sysv-rc (sysv-rc_2.85-4.1-all.deb).
dpkg says:
(translated freely from german)
dpkg: Error proceeding /var/cache/apt/archives/sysv-rc_2.85-4.1_all.deb 
(--unpack): trying to overwrite "/etc/init.d/rc" which is also in packet 
sysvinit.
Errors occured while proceeding 
/var/cache/apt/archives/sysv-rc_2.85-4.1_all.deb (--unpack)

I can install all other packages by trying to install many times until 
only sysv-rc remains but of course this is not a state I would want to 
keep forever...

Any ideas how to solve the problem?

 Tnx
