And yes, that's a bit exaggerated.
In former times you could have plenty space left on a box with 2MB RAM even when running Linux.
But, alas, nowadays the kernel alone occupies some 3 or 6 MB on its own.
Add a few 100k for BusyBox, libc, and you're at a minimum of about 4 million or even more bytes of RAM to run on top of Linux.

Sucks? Tell the kernel guys!
