#### Permissions

By default, `migrate` will write data directory files with default permissions
according to the umask it is run with. When run in the published
`registry.k8s.io/etcd` images the default umask is 0022 which will result in 0755
directory permissions and 0644 file permissions.

#### Cross building

For `amd64`, official `etcd` and `etcdctl` binaries are downloaded from Github
