The only time it's an issue is the first boot for a new system;
after that you're reusing the same key.
The question is whether that key is entirely user-entered,
or whether it includes some kind of RNG as well.
(OTOH, if it's handled entirely by the BIOS and not the OS,
then it's not a Linux problem.)
