[Lxc-users] [PATCH 1/1] Update ubuntu templates
Serge Hallyn
serge.hallyn at canonical.com
Fri Jan 21 17:10:10 UTC 2011
Rename 'ubuntu' template to 'lucid'
Add new maverick and natty templates, which do much less tweaking
of the environment. These should only be used on a kernel which
supports sysfs tagging for /sys/class/net, as udev will be running
in the container.
The natty template needed to slightly change the installed packages
for dhclient to be correclty installed.
