Hi,

I normally just count .mk files under package, which gives a pretty good
estimate:

find package -name \*.mk | wc -l
946

Good points.

Why is the rootfs so big? Kernel modules / glibc? A default rootfs
(internal toolchain, busybox) is less than 1.5MB:

-rw-r--r-- 1 peko peko 1.4M Feb 10 09:49 output/images/rootfs.tar

Around half of that is busybox, other half is uClibc.
