Description of Problem:
  If the user has no floppy drive, then the Red Hat Linux 7.3 Valhalla installer
can appear to hang or lock up when trying to make a boot floppy.  If there is no
floppy device, anaconda should probably not present the option to make a boot
floppy.

How Reproducible:
  Always.
  The problem arises when the user makes a mistake.
  There is a non-obvious workaround once anaconda becomes stuck.

Steps to Reproduce:
1. Remove the floppy drive cable from a standard computer.
2. Install Red Hat Linux.
3. On the page which offers a checkbox, "Skip boot disk creation,"
   then accidentally do NOT mark the checkbox, and instead click Next.
4. Observe an endless attempt to try to make a boot floppy.
   There is no screen activity or timeout at all.

Workaround:
  A proficient user who knows about Linux can press Ctrl+Alt+F2 to change to a
new virtual terminal, and inspect the (ps) process list for the stuck mkbootdisk
process, and kill it.  Anaconda then will report an error and allow the user to
mark the "Skip boot disk creation" checkbox.

Expected results:
  Anaconda should detect the condition of having no floppy drive before trying
to make a boot floppy.  If that's not possible, and anaconda detects a floppy
controller but cannot detect the absence of actual drive devices, then anaconda
should nurse the mkbootdisk process with a timeout period.

In general:
  More visual feedback during mkbootdisk would be useful here.
