Not even 1% of the programs in /usr/bin are relevant to the boot process.
You need those, such libraries from /usr/lib (or /usr/lib64) that they need,
some bits from /usr/share (/usr/share/hwdata in particular), probably a few
more bits and pieces that I haven't taken the time to track down.

There aren't many daemons that run before the local file systems have been
mounted. Should you happen to install one of those, _and_ it misguidedly
installs in /usr, then you'll have something to add to your minimal root
filesystem version of /usr. Using the "--existing" flag ensures that only
the files you've deemed necessary get copied, not the whole directory.
Hardest part, really, is coming up with a meaningful test. My systems,
like yours, currently boot just fine with a separate /usr file system, so
there's not much way to know if you've missed something that should, at
least in theory, have been included.
