Hi, What is a loopback device? Why is a ramdisk, with an ext2 file system called a loopback device? You can make an ext2 file system dump on your host, but you can not create a yaffs file system dump on your host, what is the criterion? Thanks. -- Kernelnewbies: Help each other learn about the Linux kernel. Archive: http://mail.nl.linux.org/kernelnewbies/ FAQ: http://kernelnewbies.org/faq/
