Hello Anders, I don't want to copy files into the rootfs, I know how to do that. It's really in the hddimg that I need to copy files, at the same level as the rootfs.
To make a short story, here's what I want to do. I want to use a usb drive to install a system so I "dd" the hddimg to this usb drive. The idea is to boot this usb drive on the target system so it can be used to accomplish various task, like installing a new system or updating or configuring an existing one. So to do that, I need to put the required files to install or configure the system also on the key. You could argue that I can still do all of this even if I put everything in the rootfs. However, I use squashfs for the rootfs (to save space), and also the files on the key must be modifiable by a user using a Windows computer (which is easy since this is a VFAT partition but not the rootfs that's not even writable). Like I mentionned in previous email, one way to achieve that is to extend the bootimg.bbclass, but I tried that and it didn't work (and I don't know why). After talking to some people, I guess that the simple solution is to write a separate script that does what I need i.e.once I build the hddimg, it just mount the hddimg and copy the required stuff on it. It's just that I would have liked to do that in the Yocto environment, but it's no big priority. The resulting real question however is how to extend a .bbclass and why what I tried before didn't work? Any idea about that?

Well, then I guess the question if what kinds of file is it, and how do you want to copy them into the .hddimg? Should they be copied into the rootfs in the .hddimg? If so, I'd suggest to create a standard bitbake recipe and just install those files into the rootfs. If it's something else, I think you need to explain it a little bit more.
