One problem (even with my solution which was to store a table on the disk)
is that, in the case of a kerneld system, the kernel doesn't know which
driver to probe to find a disk it doesn't know about. If I mount /dev/sda6,
the kernel knows to go get sd and scsi but if I mount /dev/usr it can have
no idea. And going and probing all possible devices half defeats the point
of kerneld. One possible solution is a mapping in conf.modules. Like 
alias filesystem_device_usr sd
alias filesystem_device_mnt_cdrom sr

But it, once more, requires you to tell the system where the drives are
which defeats the purpose.
