Description Milan Broz 2008-09-07 13:43:34 EDT
initcript contain this line (system with encrypted PV)

plymouth ask-for-password --command "cryptsetup luksOpen /dev/sda2 luks-sda2"

Running in text mode, it requires password twice, because first attempt fails (even witout touching keyboard!)

As I found, cryptsetup always receive on standard input 4 chars, no idea where they are from, but these are completely garbage not password.

Just tried to replace crypsetup with simple test program
while (read(0, &c, 1) == 1)

And I see the same.

Version-Release number of selected component (if applicable):


Plymouth ask-for-password should probably drain the output before asking password again.

Are you still seeing this with the latest plymouth?

I did some fixes on friday, including:

* Fri Sep  5 2008 Ray Strode <rstrode@redhat.com> 0.5.0-0.2008.09.05.1
- Fix some confusion with password handling in details plugin

Make sure you rebuild your initrd after updating with

/sbin/mkinitrd -f /boot/initrd-$(uname -r).img $(uname -r)

Seems that it works with 0.6.0-0.2008.09.05.3.f10, but tested on other confuguration.

I'll verify it on my test system later this week.
