I like it. I've got a few questions from npppd and openvpn users hitting the 4
tun limit,
dev_t dev = makedev(40, i); // from MAKEDEV :(
40 is incorrect. It is MD.

Drawback: This diff would require to patch all the existing users of
/dev/tun* in ports and the tree to add the TUNSIFUNIT ioctl. The
benefit is that you don't have to MAKEDEV all the tuns anymore and can
open up to around 1024 active tun(4)

btw., I like C and it is still my favorite language (sorry, CS
people). But it shouldn't be a problem to do simple ioctls with most
other languages except shell scripts.
#!/usr/bin/perl
require sys/ioctl.ph;
My favourite quick-and-dirty language is Python, and I consider
myself a fairly proficient Python programmer. I've never, ever, done
ioctls from Python, and while it looks indeed as if it is possible to
do so, I'm sure it'd take me some effort to get it right.
I definitely agree with your

Hi,
inspired by mikeb@'s clonable bpf patch, this slightly more complex
diff implements clonable interface support to tun(4).
The idea is to split the fixed relation between device minor number
(/dev/tunX) and interface unit (ifconfig tunY). In difference to the
current tun(4) implementation,
