I disagree!

While I just bought a 1TB disk  for $50 (USB WD Essentials), the Efika
MX only comes
with 4GB (TO2, rev 1.1) or 8GB (TO3, rev 1.3) of disk space. The
Smartbook may only
have 16GB. This is a lot of space for an ARM distro (Ubuntu Xfce is
~1.5GB) but it leaves
little room for anything else if you're into watching videos or
compiling a kernel (add 1GB)
or like to keep stuff around. I think it's rather annoying to go down
the path of having a
distro that assumes you have gigabytes of space when you may actually
only have a
minimal (512MB, 1GB) NAND flash on an ARM system as standard.

Can this be done on a per-machine basis at the installer?

As long as the armel binary doesn't use any floating point at all, it
will work, though.

Just make sure ld.so is built with soft and not softfp and armel can own it.
