I have a Digium Analog PCI Card and would like to access it from lxc
container.
I've searched the internet a lot but it seems information out there is
incomplete and a bit outdated.
It seems that bind mounting /dev/dahdi to
/var/lib/lxd/containers/ct1/rootfs/dev/dahdi does not help, since the
mount point does not appear from within the container.
Actually ct1/rootfs/dev seems completely different from /dev inside the
container.
Could you give any pointers?
Here is my setup:
$ lsb_release -a

I should have a /dev/dahdi with the above structure inside the container
in order for it to work.
How do I do that?
Thanks a lot.
