Help text

POSIX Access Control Lists (ACLs) support additional access rights for users and groups beyond the standard owner/group/world scheme, and this option selects support for ACLs specifically for tmpfs filesystems.

If you've selected TMPFS, it's possible that you'll also need this option as there are a number of Linux distros that require POSIX ACL support under /dev for certain features to work properly. For example, some distros need this feature for ALSA-related /dev files for sound to work properly. In short, if you're not sure, say Y.
