LXD を初めて使用し、ルートがディレクトリ /megalith に書き込むときに、ホスト ユーザーの UID/GID (1000 :1000) 165536:65536 の uid/gid ではありません。ここにリストされている指示に従おうとしています:
http://insights.ubuntu.com/2016/12/08/mounting-your-home-directory-in-lxd/
しかし、コンテナーを開始しようとすると、以下に示すエラーが表示されます。root subuid と subgid エントリを root:165536:65536 に戻すと、/megalith に書き込むときの UID と GID が明らかに 165536:65536 であることを除いて、すべてが正常に機能し始めます。
ルート subuid と subgid のマッピングを適切に機能させるために、ドキュメントに記載されていない、または不足している可能性があるものは他にありますか?
