So "updating it" is not so simple. I am concerned that by replacing it completely we might be going to lose accumulated improvements in our code though I do not have a complete list of them nor closely look into the current ISC's code. If no one investigated it, it need to be done. da> * Is there any barrier to replacing the current dhclient-script with da> * that that accompanies the ISC dhclient? da> The two scripts are quite different and my DHCPv6 changes currently da> are based on the ISC dhclient-script. Is it difficult for us to think two clients for IPv4 and IPv6 respectively? Importing a DHCPv6-only client looks much easier even if we use ISC's code. And, I personally think a similar way to network.subr for configuring DHCPv6 is not enough in practice because DHCPv6 client is typically triggered by RA or a combination with IPV6CP in PPP. I also like to see a DHCPv6 client in the base system, but I would like some more discussion about which implementations we can/want to use and typical use cases before it happens. Probably others have their own opinion. -- Hiroki [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iEYEABECAAYFAldZ6NYACgkQTyzT2CeTzy2jXgCgghFGk8CddZoeF7U+nQ9JHPG7 kmUAn1E9v3+4aJmcQbf8RgTl/rsrgwEn =sFzm -----END PGP SIGNATURE-----
