git annex reinit uuid|description
Normally, initializing a repository generates a new, unique identifier (UUID) for that repository. Occasionally it may be useful to reuse a UUID -- for example, if a repository got deleted, and you're setting it back up.
Use this with caution; it can be confusing to have two existing repositories with the same UUID.
Make sure you run git annex fsck after changing the UUID of a repository to make sure location tracking information is recorded correctly.
Like git annex init, this attempts to enable any special remotes that are configured with autoenable=true.
The git-annex-common-options(1) can be used.
