Comment 11 for bug 2065180

Stock noble on a Raspberry Pi Zero 2W:

```
bdrung@zero3:~$ sudo hyperfine -r 5 "update-initramfs -u"
Benchmark 1: update-initramfs -u
  Time (mean ± σ): 415.664 s ± 6.015 s [User: 166.728 s, System: 232.523 s]
  Range (min … max): 409.139 s … 422.632 s 5 runs
```

Replace duplicate calls in thin-provisioning-tools, lvm2, and cryptsetup:

```
bdrung@zero3:~$ sudo hyperfine -r 5 "update-initramfs -u"
Benchmark 1: update-initramfs -u
  Time (mean ± σ): 375.805 s ± 5.753 s [User: 140.586 s, System: 218.345 s]
  Range (min … max): 369.914 s … 382.866 s 5 runs
```

Suggested further reduction of dracut-install calls via https://code.launchpad.net/~bdrung/ubuntu/+source/initramfs-tools/+git/initramfs-tools/+ref/ubuntu/devel:

```
$ sudo hyperfine -r 5 "update-initramfs -u"
Benchmark 1: update-initramfs -u
  Time (mean ± σ): 241.626 s ± 5.278 s [User: 60.018 s, System: 166.183 s]
  Range (min … max): 235.136 s … 249.194 s 5 runs
