support for biosdevname in livecd's?

Asked by Jared Dominguez on 2012-03-22

Enabling biosdevname (described at is an option for Ubuntu and has been since 11.04. It is not yet enabled by default, but it is an option that can be enabled by passing the "biosdevname=1" option at boot. I am not sure if it is desired to allow this feature in live images (such as the Ubuntu Cloud live image), but, if it is, it seems like there may be a couple of bugs one may encounter when doing so because of a couple files in the casper package:

dell@dhcp-164-224:~/precise/casper-1.312$ egrep -r "eth" * | egrep -vi "([a-z]eth|eth[a-z]|^test|^doc|^po|^man)"
debian/changelog: * Write /etc/network/interfaces entries for eth0, eth1, eth2, ath0 and
scripts/casper-bottom/23networking: for interface in /sys/class/net/eth* /sys/class/net/ath* /sys/class/net/wlan*; do
scripts/casper-bottom/23networking: for i in eth0 eth1 eth2 ath0 wlan0; do
scripts/casper-bottom/24preseed: chroot /root dhclient eth0 3>&- 4<&-
scripts/casper-bottom/24preseed: chroot /root ifconfig eth0 down

I am not familiar with how casper functions, so I'm not sure if this would be a bug or if these files in scripts/casper-bottom are harmless. I will note that on an Ubuntu Cloud live image that I tried, passing "biosdevname=1" did not do anything, so it may be that this is not possible for that build anyway.
