Here's the block-extroot, still without the scripts for configuration, but working for a manual done configuration. It
* No longer has a /etc/config/extroot at all
* depends on block-mount to find and mount the rootfs, via the ability
add the option is_rootfs to a mount section of /etc/config/fstab
* modules are loaded based on a flag set in the kernel module config,
that indicates that the module may be needed for rootfs (all such
modules are automatically loaded)
* adds a couple of configuration options for directories that don't
exists in the image by default but may be needed for external rootfs
(e.g. a /usb dir for the rootfs mount point before pivot and /oldroot
for the old root)
* the external root is now an overlay, not a copied file system. That
means to create the filesystem, you would be best to
cp -ar /jffs/* /usb
assuming the use of mount point /usb for the external rootfs
In the case of a non-squashfs filesystem you should simply make
sure /usb is empty.
/etc/config/fstab should have a section like
config mount
option 'uuid' 'some-uuid-here' <OR>
option 'label' 'fs-label' <OR>
option 'device' '/dev/device'
option 'target' '/usb'
option 'fstype' 'ext3'
option 'enabled' '1'
option 'enabled_fsck' '1'
option 'is_rootfs' '1'
Note that the work <OR> should NOT be present; it's indictative of
different configuration options, not a keyword.
Note that you need to include the filesystem kernel modules yourself,
there are no dependencies to pull them in at the present time.

And that's my crabbing done for the day. Got it out of the way early,
now I have the rest of the afternoon to sniff fragrant tea-roses or
strangle cute bunnies or something. -- Michael Devore
