Partition disks:
Shell:
Once the partitioning step is complete, select "Back" in the debian installer to return to the list of steps the installer is working through and break out to a shell by choosing the option "Execute a shell".
The author said /target was there when I finished editing the partition and entered the shell via return. However, I tried several times and /target was only created after the Debian install started. So I couldn't proceed as the author explained.

YouTube also explains something similar in video. However, if I enter the shell before the Debian installation proceeds as shown in this video, /target is not created. My Debian installer only creates /target after the Debian installation has started.
I know there is also a way to create subvolumes after installing Debian on the main volume without this process. However, In the current version of Debian, there was no up-to-date manual showing successful results simply by following the command line. I wanted to copy, but I failed because the result was different.
I want to install Debian on a subvolume.
