Comment # 15 on bug 1201439 from andreas bittner

one more remark though, maybe to make end users life easier, dont know if this
would conflict with

plausible deniability
or similar reasoning if at all, that this initial password prompt with this
LUKS and grub2 and all, should give the user a proper error message visible
readable and observable if this makes sense?

this bug also means to me that I never actually failed at entering my FDE LUKS
password on this laptop ever before, only last night. it was totally unclear to
me what was going on.

When trying with the correct password, there is the normal grub2 menu being
shown and then I select the first entry of it to boot the kernel.

After selecting this step there is the second graphical mode password prompt
and entering the wrong password there recreates this prompt and asks again,
this would hint a simple user that the password was wrong and needs to be
reentered.

but failing the first step grub2 prompt only leads to rudimentary grub prompt
and doesnt help the user?

wouldnt this be a better service to the user when not leaving them in such low
level technical situations?

thanks.
