Hello,
I installed =E2=80=9Ctailscale=E2=80=9D application as a binary package =
in FreeBSD 13.2 running on RPi2. The architecture is arm7.
When adding the the application to startup via `sysrc =
tailscaled_enable=3D\=E2=80=9DYES\=E2=80=9D` the application hangs =
because device tun0 is not being created.
Once the device has been created manually, tailscaled will rename the =
device to =E2=80=9Ctailscale0=E2=80=9D.
The two existing flags =E2=80=9Ctailscaled_up_args=E2=80=9D and =
=E2=80=9Ctailscaled_tun_dev=E2=80=9D cannot be used to create the =
device.
For the init to work as expected, I added these lines:
```
diff tailscaled /usr/local/etc/rc.d/tailscaled
67a68
> start_precmd=3D"${name}_prestart"
70a72,80
>
>
> tailscaled_prestart()
> {
> if [ ! -c /dev/tun ]; then
> logger -s -t tailscale "Interface /dev/tun0 not found. =
Creating /dev/tun0"
> /sbin/ifconfig tun0 create
> fi
> }
```
I have no idea if this happens to other architectures and I=E2=80=99m =
not sure if this should be handled by the init script or the application =
itself.
Kind regards,
--
