Most times yes. In practice I suspect most deployed servers have something like ln -sf /usr/local/bin/bash /bin/bash Infinitely more entertaining is running unzip at the command prompt results in /usr/bin/unzip which is extremely limited compared to (installed via pkg) infozip at /usr/local/bin/unzip. At least one specific example I ran into was Play/Activate Scala framework can be convinced via "dist" target to make a zip file of all the jars necessary to run a project, and you guessed it, /usr/bin/unzip doesn't understand that zipfile format and /usr/local/bin/unzip works perfectly. So you can't have a script that automatically runs unzip because you need to run /usr/local/bin/unzip specifically. Lack of a Debian-like alternatives system is really the only systemic problem I run into on a regular basis. Then again it creates an inconsistency across multiple servers and I would not enjoy playing "update-alternatives whack a mole" to figure out which of my frontends have infozip provide unzip, and which fail.
