[opensuse-buildservice] osc build errors/warnings

Hi ;) since quite a while , Im seeing some osc/build errors "We do not have enough disk space in /etc or /dev/zero does not exist. Exit." No idea why this happends.. anyone ? "chroot: cannot run command `zic': No such file or directory" but "timezone" is already installed.. bug in /usr/lib/build/init_buildsystem when /usr/sbin is not in $PATH ?? im using build-2006.11.24-3 and osc-0.9-11.1 on 10.2
