It appears that the only way to get a complete filesystem is to generate an EXT2. So, if you really want a TAR or JFFS2 version you should: (?) 1. Configure BuildRoot 2. Build with the EXT2 FS option (even if you do not want it) 3. mount file.ext2 mnt -o loop 4. Generate the JFFS2 or TAR file from the loop mounted FS Is this correct?
