Re: why are there /bin and /usr/bin...

Take a look at the N900 where most of the user-installed applications
are on /home (well, /opt, but that's a symlink to /opt/home), which is a
32GB eMMC flash, while the root file system is a 256MB NAND flash, which
is vastly more expensive. So while the situation you are describing
might be common, it's not always true.

What I'd like to see happen here is that having /usr a symlink to /
becoming a supported configuration. I keep meaning to set up a system
like that and see what breaks, but haven't gotten around to it yet.
