Description of problem:
Cannot boot installer from diskboot.img
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. dd if=diskboot.img of=/dev/sda1 (writes diskboot.img to USB drive)
2. Configure PC to boot from USB
3. Boot PC
Gives: "This disk is not bootable disk ..." message
PC boots to installer.
Mounting diskboot.img on the loopback device shows an empty filesystem.
diskboot.img from test4 release works fine, and shows files when loopback mounted.
Things look fine when composed as an RC candidate with pungi; so something is
probably going wrong in the environment that rawhide is being built in.
Bill -- does the rawhide compose environment have loop devs? Or where's a log
and I'll pore over it to see if I see why things are failing.

patch to make pypungi spew to cli
Definitely looks like the loopback mount isn't happening. Bits are landing in
tree/images/fobpath -- that's where the image gets mounted in
scripts/mk-images.x86. Log still doesn't have error messages, but I think
that's due to stderr being lost more than anything
Should be 'fixed' in the next build.
