For a while I have been working with the rootfs provided by oneiric.tgz as supplied with the ubuntu distribution for the SabreSD board. I need to add my own files to the boot image namely, when I build the kernel I have noticed some of the modules are added to directories in /ltib/rootfs/ I have noticed that my rootfs folder is considerably smaller than the oneiric.tgz. How do I add the changes I made to the rootfs folder to oneiric.tgz.
I previously decompressed oneiric.tgz on my linux build system, copped the contets of rootfs over the top and re compressed the oneiric.tgz folder. This didn't work as the system was unbootable.
