fuse-etcd.py
A very basic FUSE filesystem built using the etcd key value
store as a backend. This driver uses the same fusepy library used by the FUSE
passthrough driver.
It's (over-)simple - paths are keys, file content in values. There's no
metadata (permissions, ownership, timestamps, etc.). Directories are just files
containing the magic string __DIRECTORY__.
Although there are clearly many shortcomings to this filesystem, some effort
has been made to provide consistency between multiple clients. This is
implemented using etcd's transaction support.
A very minimal set of tests is available in test-fuse-etcd.py.
