> Why are /usr/bin, /usr/sbin, /sbin, /bin in chroot command? Aren't these
directories empty after completing temporary system? Aren't all packages
installed in /tools/bin not in /bin, /usr/bin, /usr/sbin, /sbin?

the command sets some variables when inside the chroot. Yes these
directories are empty but when you will install the final system the sysyem
will use the programs installed in the final proper location instead of
those put inside /tools (as you can see /tools/bin is the last put inside
the PATH variable)
