Everything in tmpfs is temporary in the sense that no files will be	  created on your hard drive. The files live in memory and swap	  space.

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.
