Hi,
$ lxc-execute --name net -s lxc.network.type=phys bash
Segmentation fault (core dumped)
The problem is that the netdev structure is mostly uninitialized (only
its type is set to LXC_NET_PHYS), so if_nametoindex() is invoked with a
NULL argument:
static int instanciate_phys(struct lxc_netdev

Hi,
I had a go against lxc-create trying to debug the console issue.
There is still a serious issue: the template scripts use some 'arch'
binary, which isn't present on my system. What is that? Why not use
'uname -m' instead?
Thanks,
Feri.

The mnt directory has a good chance to already exist in the new root
filesystem, so creation and removal can be avoided. This also eases
use of read only root filesystems (no configuration necessary).

Reading the kernel documentation of devpts, I got the impression that if
the host uses the "legacy" devpts mode, root in a container can always
mount its devpts instance. Is this really so? If yes, it might be
worth noting somewhere near the lxc.pts option. And a kernel option to
