Foreword
This is my effort to create a unionfs filesystem 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
