Article note: This is a ...narrow... view. Most modern unix-like systems are absolutely lousy with binaries that behave differently when called with different names.
All the common preboot environments and small embedded linuxes have a busybox type thing where _one binary_ provides most of the POSIX environment via symlinked names. Etc.
Despite my manly looks, I am horribly timid. My romantic soul gets all clammy and shivery at the thought of running into some awful indecent unpleasantness.
