/bin system binaries for all users
/sbin system binaries for root
/usr/bin distro binaries for all users
/usr/sbin distro binaries for root
/usr/local/bin binaries managed by repository, but not by distro for all users
/usr/local/sbin binaries managed by repository, but not by distro for all root
/opt/bin/ user compiled and installed binaries for all users
/opt/sbin/ root compiled and installed binaries for root purposes
more or less? I would expect GEMs to follow behaviour?
