Hi n2n

Thanks to the stable n2n-3.0, it's super stable, fast and awsome!

However, I need to make the Linux TUNTAP device persistent for routing purpose, so I added a --persistent flag to Linux edge. Would you review and accept this PR?

By default, or re-run without persistent flag, the TUNTAP device will be deleted when edge exits.

Thanks!

Its probably better to use the existing tools to create a persistant tun device than to patch n2n - that way you can also integrate with your system-wide network configuration and use ownership for delegation.

If you are doing this by hand:

ip tap add mode tap user $RUNASUSER name $IFNAME

Oh, thanks, I didn't realize that N2N can utilize the existing TAP device.
However, it's still good to have the --persistent flag to have a N2N persistent TAP device in one go.

I do no support this one either as it looks way too specific to me and can easily be solved by other tools. Also, how would this one translate into Windows version?
