Differences between revisions 8 and 26 (spanning 18 versions)

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, will only minor convenience issues to be fixed...

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

Usage

unionfs [options] root[:root...] mountpoint
The first argument is a colon separated list of directories to merge

general options:
    -o opt,[opt...]        mount options
    -h   --help            print help
    -V   --version         print version

UnionFS options:
    -o stats               show statistics in the file 'stats' under the mountpoint

TODO

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