Downstream-only commit 118458a3fb ("sysconfig: Don't write BOOTPROTO=dhcp
|
|
|
18322d |
for ipv6 dhcp") did two things:
|
|
|
18322d |
1) Disabled BOOTPROTO='dhcp' for dhcp6 setups. This change seems to be
|
|
|
18322d |
correct as BOOTPROTO is unrelated to IPv6. The change was since merged
|
|
|
18322d |
upstream (commit a57928d3c314d9568712cd190cb1e721e14c108b).
|
|
|
18322d |
2) Explicitly disabled AUTOCONF and this broke many valid configurations
|
|
|
18322d |
using it instead of DHCPV6C. Revert this part of the change. In case
|
|
|
18322d |
DHCPV6C-only support is needed something like a new 'dhcpv6c_only'
|
|
|
18322d |
network type needs to be suggested upstream.
