私のラップトップにはUSB-Ethernetアダプタがあります。明らかに、ネットワークは通常より遅く、ブートプロセスが終了するまで現れません。私のNFS共有は起動時にマウントされません。ただし、ノートブックが起動したら、次を使用してすべての共有をマウントできます。
mount -a -t nfs,nfs4
エラーはありません。現時点では、すべてが正常です。ただし、起動時に共有を自動的にマウントしたいです。だからこれいいえNFS構成の問題。問題は、systemd、ブートプロセス、およびUSBイーサネットアダプタの可用性タイミングに関連していると思います。
NFS共有がマウント試行を放棄した後にネットワークが表示されることを示すログの関連部分を含む、私が確認する必要があるすべては次のとおりです。関連する設定ファイルが含まれていますが、私が知っている限り、デフォルト値から変更されませんでした。

更新：fstabについて要求された情報は次のとおりです。
すべてのnfsマウントには次のオプションがあります。
nfs _netdev,defaults,noatime,nodiratime,soft,retrans=6,timeo=20,retry=0,rsize=32768,wsize=32768,proto=tcp 0 0
私はsystemdで_netdevを使用します。 Filipe Brandenburgerのコメントを読んだ後、このオプションはsystemdで意味がないか有害であるかわかりません。
