[udev] saucy botching network configuration

[gregrwm]

saucy network configuration is behaving strangely. i've installed saucy via netboot, selecting openssh-server only. saucy netboot found and used my cable modem just fine, but the network configuration it installed does not find my cable modem. precise works fine, so i brought forward /etc/network/interfaces and /etc/udev/rules.d/70-persistent-net.rules from precise. surprisingly, this didn't work.

details below. precise properly obtains an address for eth0 from the cable modern. saucy doesn't, and inserts a bizarre local address instead.

under precise, which works:

[gregrwm (gregrwm)]

aha, look at HWaddr under precise and saucy. seems saucy udev isn't honoring /etc/udev/rules.d/70-persistent-net.rules.

i'd reassign to udev, but perhaps someone else has permission to do that..

udev 204-0ubuntu15 i386

[Martin Pitt (pitti)]

Sounds a lot like bug 1235162 which was fixed yesterday. Can you please try with udev 204-0ubuntu16 and check if it's working now?

[gregrwm (gregrwm)]

works now, thank you.
