Yep. Would be pretty bad software otherwise. Best to set it up so it keeps one monthly, one weekly, and 2-3 daily snapshots. Then you don't even need to think about it, and it deletes older ones automatically. You can still do manual snapshots, and it won't delete those.
The GPL states that its text must not be modified. I take this to mean (though I'm no lawboy), that if you wanted to have a license with the same terms plus some changes (the butthole rule), you would have to rewrite the whole thing. It would not nearly be a "GPL license".
This is very important nitpicking I'm doing here, okay?
Neat! I was just thinking, if it starts updating the kernel as you turn it off, you'd have to wait a minute for it to finish. M$ style. Has that never happened?
I don't think the first two are distro specific, more a question of mindset. Unless there are distros that force update your system like some other OSs, which could cause the second picture to happen more often.
This is part of my new setup ritual right along uBlock, DDG, and more. Shame that this is the best choice we have for a browser.
