Hello Chris, > a) How does a laptop turn on unintentionally? ;-)
It happens from time to time on my Dell Latitude 9420. I've shut the system down at evening and later (or the next morning) I saw that the display was on and waiting for the passphrase. It even happened twice when it was stored in my laptop case. It seems that this problem is sporadically seen on Dell laptops, maybe a hardware fault. But it could also happen on any other laptop if you accidentally selected reboot instead of poweroff and closed the lid, or if the laptop has a power-on-lid feature. > Consider that such a system would constantly be powered on > automatically (Wake-On-LAN or similar features of servers)... in such a > case, if cryptroot keyscript wouldn't finish in due time (e.g. because > no one enters the passphrase or so), it might end up in a > powerup/powerdown cycle... which is probably of no good for the > hardware. Well, then don't enable it for servers? The patch doesn't add a timeout by default, only if defined in crypttab. Best Regards, Roland
