修正する

最近、SSDをより大きなSSDに置き換えました。使ったクローン属既存のディスクを新しいディスクに複製します。その後GPartedライブ既存のパーティションのサイズを変更するには、スワップパーティションをディスクの端にスライドさせます。また、Ubuntu 16.04から18.04にアップデートしました。

上記の手順を正常に完了した後に実現しました。起動時間が長くなります。同様のスレッド（下のリンク）を見つけ、そこで提案を試しました。しかし、ブート時間はディスク交換前の時間ほど短縮されませんでした。

これは私の元のテキストです/etc/fstab。

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/sda1 during installation
UUID=e15b2ef7-c32d-46f5-a3a8-4bdc60285b4e /               ext4    errors=remount-ro 0       1
# swap was on /dev/sda5 during installation
UUID=3a0c2581-52f2-4c92-9c4a-09d3f0258c05 none            swap    sw              0       0
/dev/disk/by-id/usb-Generic_USB_Flash_Disk-0:0 /mnt/usb-Generic_USB_Flash_Disk-0:0 auto nosuid,nodev,nofail,x-gvfs-show 0 0

UUIDパーティションを交換した様子を見るとswap黒子コマンド出力：

/dev/sda1: UUID="e15b2ef7-c32d-46f5-a3a8-4bdc60285b4e" TYPE="ext4" PARTUUID="000d7e8b-01"
/dev/sda5: LABEL="swap" UUID="839f9d78-77b2-491d-808d-8cd551a9eeef" TYPE="swap" PARTUUID="000d7e8b-05"

/dev/disk/by-id/usb-..私もこれが私がGParted Liveを実行しているUSBスティックであると信じているので、それをコメントしました。なぜまだそこに定義されているのか分かりません。

/var/log/boot.log次のように表示されます。

これシステム分析コマンドは以下を通知します。

Startup finished in 36.037s (kernel) + 10.847s (userspace) = 46.885s
graphical.target reached after 10.835s in userspace

開始時間を改善するにはどうすればよいですか？

「修復」ファイルがあるようです。

/etc/initramfs-tools/conf.d/resume

これ以上見つからないUUIDを指します。スワップパーティションの正しいUUIDを指すようにファイルを変更して実行できます。

sudo update-initramfs -u

以下のバグレポートリンクのコメント＃16と＃17をご覧ください。

https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1763611

あなたの状況とバグレポートの状況には違いがあります。

  • あなたの場合はスワップパーティションを使用しています
  • バグレポートでは、スワップファイルが使用されます（したがってスワップパーティションがないことに注意してください）。
