[lxc-users] no network in vivid image? - addendum

[Fajar A. Nugraha]

You DO know that utopic will reach end of life in July?
https://wiki.ubuntu.com/Releases

If you absolutely want the latest released version, I'd suggest using
vivid in privileged mode (if you have some software that depends on
systemd), or vivid + upstart in unprivileged. Bear in mind though that
vivid will be EOLed in January, so be sure to upgrade before then.

If this is for production/long term use, then I highly suggest
sticking with trusty instead, adding ppa's to get latest version of
whatever-specific-software-you-need.
