[lxc-devel] [PATCH 2/4] oracle template: prevent mingetty from calling vhangup(2)

[Serge Hallyn]

Quoting Dwight Engen (dwight.engen at oracle.com):
> This is needed when using the user namespace since the kernel check does
> not allow user_ns root to successfully call vhangup(2), and mingetty will
> quit in this case.
