I have been digging on how hostid works on Linux versus other UNIXes. Check: http://lists.alioth.debian.org/pipermail/pkg-zfsonlinux-devel/2013-February/000005.html Perhaps a quick and easy solution for this issue will be to check if /etc/hostid is already configured on the system, and if not, just set it to a random value on the postinst of coreutils. Something like: if [ ! -f /etc/hostid ]; then dd if=/dev/urandom bs=1 count=4 of=/etc/hostid 2>/dev/null fi What do you think?
