== 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
