Hello,
CONFIG_DEVTMPFS_MOUNT=y
does not fix our problems here, we need the changes to /etc/init.d/udev I
mailed earlier.
The reason is that we start a complete debian system as initramfs. In this
case CONFIG_DEVTMPFS_MOUNT=y does nothing. As there is no devtmpfs mounted the
bugs in /etc/init.d/udev are triggered: it tries to mount a tmpfs (instead of
devtmpfs) and even this fails because it calls mount erroneously.
Probably debian systems running custom kernels built without
CONFIG_DEVTMPFS_MOUNT=y will start, too, if /etc/init.d/udev is fixed.
Regards,
