Description Alexander Dupuy 2006-07-11 00:32:16 UTC 
Description of problem:

If you attempt to update the installation second-stage boot images on a machine
that has a serial port as the system console, the /usr/lib/anaconda-runtime
readmap program tries to read the current keymap with a KDGKBENT ioctl on
/dev/console.  While that will work when the system console is a VGA+KBD tty, it
fails when the system console is a serial port (like /dev/ttyS0).  As a result,
the second stage boot images will not work correctly, and an attempt to install
them will fail with an error message like "Failed to read keymap info: Success"

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

anaconda-11.0.5-1

How reproducible:

Every time

Steps to Reproduce:
1.set GRUB configuration to boot with serial console "console=ttyS0" and reboot
2.install anaconda and ISO contents; run buildinstall and update install stage2
3.try installation using VGA+KBD console
  
Actual results:

installation displays error message in dialog box

    Failed to read keymap info: Success

(however, after clicking on OK button and continuing, installation appears to
complete successfully

Expected results:

No strange and confusing error message, just the installation screens.

Additional info:

The following patch eliminates this problem (also attached):
