Basically, the network configuration isn’t stored when sys-net is shut down.
PROS:
- When you start
sys-net, your wifi antenna doesn’t scream SSIDs (and potentially passwords) you’ve previously connected to, which, depending on your circumstances, can be beneficial. (If someone is listening, they won’t hear “STARBUCKS WIFI? STARBUCKS WIFI? WHERE ARE YOU? IT’S ME! MAC ADDRESS XX:XX:XX:XX:XX:XX! REMEMBER ME? I’M BACK!”) - If something does get into
sys-net, it’s gone with a simple reboot ofsys-net(at least, that’s the plan).
CONS:
- You’ll basically have to enter in passwords/keys every time you start
sys-net. Some people consider this an inconvenience. - There is potential that you could confuse some wifi access points (particularly corporate networks that require installed certificates, etc.), setting off their man-in-the-middle precautionary measures (If you’ve ever tried to
sshinto a completely different machine with the same IP address as one you’ve connected to before [listed in~/.ssh/known_hosts], it’s similar to that…), causing the access point to potentially refuse to talk to you. (Unlikely, though…)
Your choice whether you think this will benefit you. It all depends on your circumstances
