When JAMF quickadd is run, its script symlinks /usr/local/bin -> /usr/local/jamf/bin/jamf
This causes an issue when installing popular scripts such as brew (homebrew) which appears to rely on usr/local/bin being a directory, not a symlinked path. ie you get the following error:
mkdir: /usr/local/bin: Not a directory
Failed during: /usr/bin/sudo /bin/mkdir -p /usr/local/bin
since bin is symlinked to bin@ -> /usr/local/jamf/bin/jamf
(btw, yes, PATH doesn't follow symlinks)
