Re: password-db failure?

Looks like that worked. I doubt my virtual machine has direct enough
hardware access for the hw_random device - it's a VPS. Probably also why it
didn't get much entropy - presumably it only gets packets that are forwarded
to it, and it has no mouse/keyboard.

Anyway, maybe it should spit out warnings or something if /dev/random
appears to be blocking for a long time? Or maybe /dev/random shouldn't be
used at all if it's not necessary - one of those things where it tells you
"if you have a good /dev/random and need maximum security, use this switch".

Or just use it for seeding?

Anyway. Works now.
