Foreword

This is my effort to create a unionfs implementation which is probably slower but way more flexible than the current in-kernel unionfs solution. Currently it's almost fully usable, the only problem is new file/directory creation which I will fix soon...

I'm open to patches, suggestions, whatever (at radek@podgorny.cz)...

Why choose this stuff

  • The filesystem has to be mounted after the roots are mounted when using the standard module. With unionfs-fuse, you can mount the roots later and their contents will appear seamlesly
  • You get caching which speeds things up a lot for free
  • You get nice stats (optional)

Why NOT choose it

  • Compared to kernel-space solution we need lots of useless context switches which makes kernel-only solution clear speed-winner

Available parameters

  • --roots=/root1,/root2

  • --stats

TODO

  • Add support for creating directories
  • Add support for choice which roots are read-only and which are not
  • Add cache controls
  • Handle writing to /stats intelligently
