This seems slightly bogus for a number of reasons:

1. initscript doesn't obviously rdepend on busybox so it's not obvious
that the latter will always be available;

2. it should probably be using ${base_bindir} and ${bindir} rather than
hardcoding absolute paths.

3. the whole idea of creating a shadow "/usr/bin" underneath what's
meant to be a mountpoint seems rather dubious to me. 

4. this seems like distro policy and not something that really belongs
in oe-core at all.  For systems where ${bindir} and ${base_bindir} are
on the same filesystem (or even are the same directory) this script will
just make bootup slower without achieving anything useful.
