List-Id: The user-mode Linux development list List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: user-mode-linux-devel-bounces@lists.sourceforge.net Errors-To: user-mode-linux-devel-bounces@lists.sourceforge.net To: user-mode-linux-devel@lists.sourceforge.net I want to loopback mount a jffs2 filesystem, and this filesystem has incestuous knowledge of flash devices for wear levelling and stuff, so it will only mount an actual flash device and not a normal block device. There's a way to make a loopback device look like a flash device, letting you loopback mount jffs2, but it involves recompiling the kerenel to add support for it, and of course I went "User Mode Linux"... Except that UML disables the flash menu entirely. Basically, I need to be able to enable MTD_BLOCK so I can go: losetup /dev/loop0 /path/to/imagefile.jffs2 insmod blkmtd erasesz=256 device=/dev/loop0 mount -t jffs2 /dev/mtdblock0 /mnt This shouldn't need any actual flash hardware. It's just layering another translation layer on top of loopback. Suggestions?
