// to get back into your system. This allows an admin to write the current
|
|
// bootstrap "index" into a special file on disk to override the mechanism preventing
|
|
// a second token bootstrap. The index will be retrieved by a API call to /v1/acl/bootstrap
|
|
// When already bootstrapped this API will return the reset index necessary within
|
|
// the error response. Once set in the file, the bootstrap API can be used again to
|
|
// get a new token.
|
|
//
|
|
// Q: Why is the reset index not in the config?

|
|
// accidentally allowing bootstrapping yet again after a snapshot restore.
