I cloned a 1.2 GB user mode linux file w/ ext3 fs (Gentoo Linux) into a 2.0 GB bigger file with ext4. Trying to boot the image however I always get :
Code:

...
 [ ok ]
 * Checking local filesystems  ...
stable: clean, 81157/122160 files, 265527/488281 blocks
 [ ok ]
 * Remounting root filesystem read/write ...
mount: cannot remount block device /dev/ubda read-write, is write-protected
 * Root filesystem could not be mounted read/write
 

probably PEBKAC - but what d I miss ????

toralf,

Two thinks come to mind.

DEVTMPFS in your kernel (and the mount option that appears when you select it).

Or adding udev-mount to the sysinit runlevel.

both aren't the culprit :-(
(and the fstab entry I've already adapted)
