[LinuxBIOS] qemu images

[Nathanael D. Noblet]

Hello,
   I have a semi related question. I see that the OLPC project uses
buildroot to create a root filesystem. I've done the same for a few
projects. I'm wondering though, how they convert the filesystem to a
disk image. I went over the docs on the wiki and used google, and I
don't know how they get a disk image from the filesystems it creates.
