After reading the discussion in bug 317337 again, I think that the
change should be announced on a wider scope, e.g. the gentoo-dev mailing
list. Just to make sure that everybody (prefix people in particular) is
on the same page. And especially, if we go for a retroactive change.

Also, trying to summarise it in a table:

    SYSROOT    ESYSROOT
    -----------------------------------------
    /          ${BROOT}
    ${ROOT}    ${EROOT} (= ${ROOT}${EPREFIX})
    other      ${SYSROOT}
    -----------------------------------------

Is this correct? What happens if both ROOT and SYSROOT are equal to /?
First or second row?
