In a situation like this, when I have control over /etc/passwd and can create accounts as I please, then I might have a single account, let's say /home/amturing, then (as a subdirectory) another account /home/amturing/amtgo. Unruly apps that benefit from UID/GID regimentation can be constrained in this way. The whole app assuming ~amtgo is also helpful. EDIT: I also remembered this useful advice on prefixing private shell scripts in your path with a comma: https://news.ycombinator.com/item?id=31846902 https://news.ycombinator.com/item?id=31846902
