title: is there something like alternate data streams on any linux filesystem?
body: <p>On Windows NTFS there is a nice but mostly unused feature called 
  "Alternate Data Streams" (ADS) which I recently used in a hobby-dev project.</p>
  
  <p>On Mac HFS+ there is also a similarly nice but mostly unused feature called "named forks".</p>
  
  <p>I am thinking of porting this project to Linux, but I do not know if any Filesystem on linux has such a feature?</p>
