Ubuntu 15.04がUpstartで15.10で正常に起動し、SystemDでの起動に失敗する
Systemdを使用した15.04と15.10の両方で緊急シェルにしかアクセスできず、upstartは問題なく動作するため、この問題を解決する方法はわかりません。バージョン全体でこれに苦労したので、助けていただければ幸いです。
ここで私のdmesgの最後の数行：

OKこれはばかげていますが、USBドライブの/ etc/fstabエントリに関係するエラーの解決策が見つかりました。
/ dev/disk/by-label/SeqData1/mnt/SeqData1 nosuid、nodev、nobootwait、nofail、noauto、x-gvfs-show 0 0
これをコメントアウトする必要があり、systemdが正常に起動しました。 USBドライブのこのエントリがそもそもそこにあった理由はわかりません。最初にnofailとnopootwaitを使用してみましたが、それは役に立ちませんでした。これについてはまだ混乱していますが、問題は解決しています。
