[lxc-devel] Using initctl inside a container with upstart?
Hi all,
is it safe to use initctl in a container using upstart (as ubuntu lucid)?
Especially, upstart-init uses an abstract unix-socket:
connect(3, {sa_family=AF_FILE, path=@"/com/ubuntu/upstart"}, 22) = 0
Is this socket separated from the parent (host) namespace, so the
container can't affect the host-system?

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.

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

[lxc-devel] Question using macvlan
Hi, I think this is a frequently asked question, but I can't find the answer ... The host machine has 2 NIC, eth0 and eth1. eth0 is used a an internal and eth1 is used as an external interface. The lxc-container is setup using a macvlan interface in bridge mode on eth0 with a static ip address. I can't figure out how the container can communicate with the host! I found an advice to create a macvlan for the host either: I tried that but without luck. It would be nice if someone could me direct to the right direction here.
