 Hi Noé,

 While you're working on this, there is something else that you may be
interested in doing.

 Currently, the iso image that is generated is not really the root filesystem,
but it contains a cpio image with the real root filesystem. But in fact, there
is no good reason to work that way, and it really complicates the build.
Instead, it would be a lot more logical to create a real iso9660 root filesystem
using the RockRidge extensions.

 That would also allow the iso9660 fs to finally use the ROOTFS_TARGET
infrastructure, removing a lot of cruft.

 If you're willing to work on this, you can add it as an additional patch to
your series. It's very likely that it will need a couple of review cycles, so be
prepared for that :-)
