: Looking at the patch, the change seems deliberate. At the same time a

Because redhat included references to 2.0 to their distribution,
and their scripts just die if do not see any ip_forward.
are enough experienced (as rule) to figure out what is the problem.
2.2 will look better, if it will be compatible with 2.0 here.

So, ip_forward and ip_default_ttl are made compatible with
2.0 both in /proc/sys sense and in binary sysctl() level.

Another variables can be set with per-interface granularity now,
so that they are moved to /proc/sys/net/ipv4/conf/{all,default,device}/
directory. Also /proc/sys/net/ipv4/route/ directory is added
to control routing tables, and /proc/sys/net/ipv4/neigh/
to control arp tables.
