Public bug reported:
The usb-hdd images created with live-build do NOT have the first
partition flagged as bootable. This way, when the image is copied to a
pendrive, it will not boot in some BIOSes. When lb_usb_binary script
sets the boot flag, the image is mounted as a loop device *with* an
offset (thus accessing the contents of the first partition). This is
wrong. It should set the boot flag earlier, when the image is mounted as
a loop device *without* an offset (thus accessing the mbr). The fix is
trivially simple, and a patch is attached.
What is expected to happen:
The lb_binary_usb script should flag the first partition as bootable in the
image mbr.
What happened instead:
The lb_binary_usb script sets the boot flag in the wrong moment, and as such it
does not work.
Using Ubuntu Precise 12.04 amd64.
Live-build 3.0~a24-1ubuntu32.
