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
- install liblzo2 and libz (build-time dependencies)
- install rust and cargo
- clone repo
