Oh god - the amount of times I've had this discussion with people over
the years who think ZOMG its version n-1!!!

It takes a while to figure out how this stuff works with real linux vs
the hobby distributions - and I'm still seeing stuff fixed in RHEL
packages that aren't even fixed in upstream versions (even though the
version number is newer!).

One such problem I'm currently working with RH on fixing is IPv6 PD
requests over PPPoE connections using dhclient. We've found the root
cause, and now a fix is being investigated. This still doesn't work with
the ISC version - even though its a newer version number.
