Hello,
I'm trying to create a device node in the generated rootfs image: /dev/net/tun. It
is required for openvpn to work. Adding it in the living system is as trivial as
"mkdir /dev/net;
mknod /dev/net/tun c 10 200", but I want it to be there with no manual
intrusion required.
I tried several ways:
* IMAGE_DEVICE_TABLES
* IMAGE_DEVICE_TABLE
* adding /dev/net/tun file to the package
* adding a node file to the IMAGE_ROOTFS in rootfs postprocess script
* using postinst script that creates the node
None of it worked.
What is the way /dev is populated? Where do all those 256 (why so many btw?)
pty* nodes come from? How do I create the new node?
Your kernel needs to be built with CONFIG_TUN (not common, you'll
probably need to rebuild it with this option). Once this option
is in place, udev will automatically create that device for you.
Note: if you add this as an module (CONFIG_TUN=m) the device will
be created when you install the module.
