I noticed that links to BB applets are scattered across /usr/bin, /usr/sbin, /bin, and /sbin. Given TCL's anti-scatter philosophy, I was a bit surprised by this. I was expecting one directory or two at the most (e.g., links for busybox applets in /bin, links for busybox.suid applets in /sbin).
The question is motivated by curiosity, not criticism. I'm sure there is a practical or historical reason for this, which would be interesting to know.
