You also don't have the flexibility to replace the kernel. Or glibc.
But you do, don't you? It'll take you months to replace them, or years to rewrite, but you *can* do it.
I agree. We had once new machine with 32 bit CPUs and 8GB of RAM - that time RAM was cheap, but amd664 architecture didn't exist yet,- and standard kernel only supported 1 GB user space. Not changeable in kernel config. It took me between one and two weeks to find hardcoded boundaries, and change them; 3.5 GB for userspace was max I could squeeze leaving the rest to kernel + stack + ... and still having stable solid system. That was decent solution.
I wholeheartedly agree with Keith.

That is the freedom that open source software provides that proprietary OSes do not; it does not come with the additional promise to provide exactly the software you specify.
