If the problem happens with inet6 routes only, why do you need to > revert r248895 ? For consistency. Either I populate own iface-routes for both, inet and inet6, or I clean both. The latter is what my script has been doing for some time (I think I wrote it when I tested 9.1-RC), so for me it's much less effort to make my script working by reverting r248895 instead of adding another one which cares about inet (v4) only (for the moment). Probably net.add_addr_allfibs will also influence inet6 routing as well in the future, then I'll redo my rc.jails_fibprepare.
