[pkg-cryptsetup-devel] Bug#994682: cryptsetup-initramfs: Poweroff timeout for cryptroot

[Roland Tapken]

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.

Well, then don't enable it for servers? The patch doesn't add a timeout by 
default, only if defined in crypttab.
