This release was created by: | |
* Building a combined binary of `tailscale` and `tailscaled` | |
* Using the build option `--extra-small` | |
* Compressing the binary with UPX | |
To use both programs, rename `tailscaled-OS-ARCH` to `tailscaled` and create a symbolic (`ln -sv tailscaled tailscale`) link. |
