A pi can definitely be used, but you may get much better performance for a similar price getting a refurbished pc, adding a second nic, and installing something like opnsense.

It’s the 24 hour wait portion that makes me continue to think Google is not acting in good faith. Any or all of the following steps - hiding it behind developer options, a warning about being coached, and even the restart to disconnect any live sessions, I could buy as reasonable efforts to protect people. 24 hours is ridiculous though. They also didn’t seem to address what happens if you factory reset your phone or get a new one. Would it be a days wait each time? A lot of us will be fine with adb during that time period, but an “intermediate” user who likes f-droid but isn’t comfortable with the adb command line shouldn’t have to wait a day to install their apps.

I’m going to be testing XigmaNAS. If I’m not crazy about it I’ll likely just run a pure install of FreeBSD
