 We want a way to supress (or collect elsewhere) all kernel output and
 leave the sysinst screens alone - it is not just this particualy kernel
 printf, but also thermal sensors changing state or USB devices being
 pluged/unpluged that disturbs the curses display.
 
 Unfortunately it is not as trivial as everyone seems to think. We have
 an ioctl to replace the console device with some other device, but none
 to "mute" it (and only collect the output from /dev/log instead).
 
 Anyway, this is true for all kernel output, not this line specifically
 (especially since "early in sysinst" is a very unlikely time for it
 to happen on most hardware).
