- Update of rootfile not required.
- Updated ipfire traceroute patch.
- Changelog
    2.1.2
	*  Fix unprivileged ICMP tracerouting with Linux kernel >= 6.1
	   (Eric Dumazet, SF bug #14)
    2.1.1
	*  Interpret ipv4-mapped ipv6 addresses (::ffff:A.B.C.D) as true ipv4.
	   There are no ipv4-mapped addresses in the real network which we
	   operate on, so use just ipv4 in such cases, but allow users
	   to specify it this way for convenience.
	*  Return back more robast poll(2) loop handling.
