我的系统有一个加密分区。
在启动过程中，屏幕显示消息和 cryptsetup 要求我输入密码之间有相当长的延迟（大约 10 秒）
我可以确认dmesg
[ 2.739272] hid-generic 0003:1532:025C.0012: input,hiddev6,hidraw17: USB HID v1.11 Device [Razer Razer BlackWidow V3 Pro] on usb-0000:06:00.3-6.2/input3
[ 16.521082] EXT4-fs (dm-1): mounted filesystem with ordered data mode. Opts: (null). Quota mode: none.
等待密码提示十秒钟，然后输入密码，然后加密，最后安装。
看看这个问题和答案https://askubuntu.com/questions/1029598/xubuntu-18-04-kernel-takes-long-to-boot让我认为它正在尝试查找 SWAP，但我已禁用它sudo swapoff -a，并在 fstab 中将其注释掉：
# /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>

并确保无法恢复：
cat /etc/initramfs-tools/conf.d/resume
RESUME=none
sudo update-initramfs -uk all
这是我的 blkid 输出：

在要求我输入密码之前系统正在等待什么？这次可以减少吗？
