Description Evan McNabb 2009-08-27 15:30:46 UTC
Description of problem:

This is a minor annoyance that I noticed when using a dracut created ramdisk. On F11 default, the LUKS password prompt for /home is displayed correctly:

/home is password protected: 

But when using dracut, the prompt is displayed but then text from a loading module is printed over it:

/dev/dm-1 is password protected:IBM TrackPoint firmware: 0x0e, buttons: 3/3
input: TPPS/2 IBM TrackPoint as /devices/platform/i8042/serio2/input/input7

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

How reproducible:
Every time

Steps to Reproduce:
1. Followed steps in:
Actual results:
Prompt isn't clear to type in password

Expected results:

Additional info:

(one other related note which might be best addressed in a different BZ: the prompt previously said /home was encrypted which is more intuitive for the average user than /dev/dm-1)

If your root is not encrypted, add "rd_NO_LUKS" to the kernel command line. 
At that point of time, dracut does not know about where the devices are mounted to (no /etc/fstab available), so it can't display that.

The kernel output about the TrackPoint is strange...

Is the plymouth boot progress bar displayed properly?

Comment 3 Evan McNabb 2009-08-27 16:21:48 UTC
Ok, I looked into this a bit more. The plymouth password prompt is displayed correctly. Also, if I disable plymouth completely at boot, then the text password prompt is displayed correctly.

It only seems to happen when I hit Esc while plymouth is loading to go back into text mode (which I sometimes do to get more verbose output). I wonder if some of the modules loaded when plymouth starts (trackpad in this case) take longer to load and appear after the text prompt is displayed. Fortunately this problem isn't a big deal.

can't fix this.. "quiet" should prevent the kernel from printing messages to screen.
