I've wanted this for a while; when I'm done with my computer, I don't mind it staying on a bit longer to do this, rather than when I next turn it on when I (presumably) want to do something. Great add!
You know what else would be awesome? "Update, reboot, and (just this once) automatically login"
It would be super useful for when I'm alone at home working but want to do updates over my lunch break.
I think an issue is, this sets up your computer to have a way to bypass putting your password in on boot. If you don't care about security too much and don't have things like secure boot and encryption, then that's bypassable anyways... But otherwise, I'd be concerned about introducing systems that specifically bypass security.
As long as you have to put in your password when you enable this I feel like it's fine. There's plenty of times, especially on Linux, where the user has to bypass security limitations to do this (sudo being the most obvious example)
The issue is, when doing sudo, you have to put in the password when doing sudo. In this case, you put in your password, some flag is set, the computer does a full reset, and then after it reads the flag and decides to bypass the password system. That sounds like just a step away of figuring out how to set this flag without a password to bypass logging in.
Gnome has been pissing me off for a while. Time to take a try of kde
I used GNOME for years because people say it's "easier", but it's not "easier" it's just simpler. I almost never need to go to the command line with KDE whereas with GNOME it was a weekly occurrence. I am frankly embarrassed I wrote off KDE for so long.
