So you’re saying you don’t like the choice in Linux? On a given distro, there’s usually one right way and maybe 2 other ways. Learn the right way for your setup and you’re good.
If you’re using Network Manager, do it the Network Manager way. If you’re using Debian as a server, do it the Debian way (`/etc/network/interfaces). If you’re using SUSE, do it the SUSE way (YaST).
If you don’t want to deal with it, use DHCP (usually default) and set the static lease on your router using the MAC address. That’s better anyway because you can change all of your static leases in one spot if you ever need to.
2 is usually install, using a live version of Linux kinda sucks.
