Hi Willem,
thanks a lot for the script, I fixed some nasty things but I was happy
to play with it :)
Do you mind to modify the script in order to have '/var/tmp' not being
sorry, I meant '/var/run'
ok, changed it in the attached script (and added the patches you posted
and some other tweaks)
mounted as a tmpfs, so the mechanism within lxc can 'shutdown' /
'reboot' properly ?
but a halt from inside the container isn't handled properly: the
init-process still remains ...
Any ideas?
Thanks

interesting attachment.
could we take it in lxc as a new template exemple
in scripts/lxc-ubuntu.in ?
Sure!
Attached I have the polished version with GPL, author and based-on ...
Please feel free to include it into LXC.
It will need few adaptations using some @xxx@ but easy to change.
ok.
