Description Roderick Johnstone 2007-05-21 12:25:31 EDT
Description of problem:
Cannot boot installer from diskboot.img

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

How reproducible:
Every time

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
Actual results:
Gives: "This disk is not bootable disk ..." message

Expected results:
PC boots to installer.

Additional info:
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.

Comment 7 Jeremy Katz 2007-05-21 23:26:17 EDT
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.
