Technically we don't know if a `virtiofs` file system supports `inotify`
or not, but it seems like it's mostly used inside virtual machines
provided by:
- OrbStack (`inotify` works)
- Docker Desktop (`inotify` works)
- Lima (`inotify` works with flag)
- Colima (`inotify` works with flag)
- QEMU + virtiofs setup (`inotify` doesn't work without extra setup)
