For proper functioning Softnet binary requires two things:
* a [SUID-bit](https://en.wikipedia.org/wiki/Setuid#SUID) set which effectively gives it `root` privileges
* a [SUID-bit](https://en.wikipedia.org/wiki/Setuid#SUID) is set on the binary or [passwordless sudo](https://serverfault.com/questions/160581/how-to-setup-passwordless-sudo-on-linux) is enabled, which effectively gives the binary `root` privileges
* this is needed in order to create [`vmnet.framework`](https://developer.apple.com/documentation/vmnet) interface and perform DHCP-related tweaks
* the privileges will be dropped once all of the initialization is completed
* to be available in `PATH`
* the privileges will be dropped automatically to that of the calling user (or those represented by the `--user` and `--group` command-line arguments) once all of the initialization is completed
* the binary is available in `PATH`
* so that the Tart will be able to find it
