That's actually a 68% reduction. The size is 32% of the old size. :-) And in fact, can you actually make a busybox-based debian rootfs in practice - I don't think the dependencies will allow it? So another relevant comparison is with a straightforward arm debootstrap rootfs, which is 120MB, (with the size-doubling apt-cache thrown away), which shrinks to 74MB if you throw away all of /usr/share/doc and most of zoneinfo (which produces a mostly-working but less-bloated fs). That would be an 87% reduction. (although we are missing some useful things like perl).
