[Lxc-users] how to execute shell command in container ?

[Sebastien Pahl]

There is a command call lxc-attach which does just what you want.
However you need these patches:
http://lxc.sourceforge.net/patches/linux/2.6.35/2.6.35-lxc1/

They don't apply on newer kernels:-(

Is there a newer version of the patches somewhere? How far along is
the process of getting them into the kernel?
