Thanks. The -I <nothing> sounds like the better alternative, as from |
24 |
your description elsewhere removing the duid would simply create new ones |
25 |
each time, filling up the slots on the server unnecessarily, while the -I |
26 |
disabling shouldn't use the functionality at all, which would be the same |
27 |
as having it not compiled in. |
28 |
|
29 |
With that caveat, having it on by default and the livecd thing turn it |
30 |
off seems a bit more reasonable -- except then the livecds won't of |
31 |
course work with ipv6 DHCP then, as it's required there. Given limited |
32 |
space on the CD and a desire to use it on ipv6 nets, I don't see a way |
33 |
around disabling it there 200 uses filling up garbage slots on the server |
34 |
or not. Well, there's a hack, two in-path versions, a normal version |
35 |
script stub that adds the appropriate deactivating -I and an ipv6 or |
36 |
whatever version that doesn't, but that's a hack and not really |
37 |
satisfactory. |
38 |
|
39 |
Are any other LiveCDs using it yet or otherwise providing IPv6 DHCP |
40 |
functionality? What do they do? Surely it's not just a Gentoo problem. |
41 |
|
42 |
I still think IUSE=dhcp-uid is about as descriptive as it gets, and |
43 |
coupled with a decent use.desc.local entry and perhaps an elog notice of |
44 |
some sort, that should be fine. |
