Please consider the following patch.
This one makes the `live' script handle the root= kernel
parameter in cases other than using `plainroot' or network boot.
In particular, it allows one to override the results of
autodetection (in case one gets several devices holding Debian
Live attached to the computer, or for debugging.)
Personally, I use it to specify an LVM logical volume to be used
as the Debian Live ``root'' filesystem.
