defrag-dirs

A simple directory index "defragmentation" tool since e4defrag only handles regular files It works by moving all directory contents into temporary directories and then replacing the old ones.

Caveats:

• Will interfere with any process that tries to access the directories at the same time.
• Does not preserve xattrs, acls or timestamps of directories. Metadata of other dir entries is preserved
• If an error is encountered in the middle of a move files may be left stranded in a temporary directory

Build

• install liblzo2 and libz (build-time dependencies)
• install rust and cargo
• clone repo
• cargo build --release
• target/release/defrag-dirs --help
