My original intention was that META_BG would place the bitmaps and
inode tables at the beginning of each metagroup by default, but that
the constraints about where to put the bitmaps and inode tables would
be completely relaxed from the point of view of requirements by the
kernel and e2fsck. Unfortunately while I had patches which removed
the constraints checking, they never made it into mainline of either
the kernel or e2fsprogs, sigh.
