// Regression for the startup failure observed when a second OS account (or a
// leftover root-owned directory) already created the shared /tmp locations:
//
//	unable to create ImageDir: "mkdir /tmp/generated/content: permission denied"
//
// The historical defaults (/tmp/generated/content and /tmp/localai/upload) are
// shared across every user of a machine. On macOS /tmp is routed to the shared
// /private/tmp for all accounts, so the first account to run LocalAI creates the
// parent with 0750 perms and locks everyone else out. The defaults must instead
// be scoped to the current user so unrelated accounts never collide.
