RedHat don't support installs on removable drives - see:


But, looking at the anaconda source - in partedUtils.py at around line 833:

             if isys.driveIsRemovable(drive) and not flags.expert:

So it looks like if you boot the installer with 'expert' on the command 
line it may work.

I've just tried this, I can get disk druid to see the USB drive - but I 
did have to 'go back' and re-try disk druid before it found the USB 
drive - I didn't get as far as installing (I don't have a 1GB USB 
stick), but it may work...
