Yes. In a typical live USB session, all changes are written to the RAM, so they are lost on the shutdown. Some live USB supports persistent storage, but I think it's not so common.

I see. Before the switching, you may want to try Linux on Windows using WSL2 or VirtualBox, etc. Also, Mint and other distros provide bootable image, so you can try it without installing Mint on your machine. Good luck!

Kernels are usually intalled in '/boot', and we usually install new kernels via a package manager (gnome-software, pacman, dnf, etc.). What distro and package manager are you using?

New kernel may introduce regressions. See this similar issue on kernel 6.10.3, or try another version of kernel on startup if it's possible.

Can you try true instead of True?

Values of type boolean must either be the string true or false.

You can get 50 items at most with limit=50. Try

Thankfully, with a modern minibuffer UI package (Ivy or Vertico, for example), we don't need to remember arcane key bindings to run rarely used commands. To run such command, just run M-x and enter a substring of the command name. This video (posted here months ago) explains this topic very well.

For Emacs's help system (Info), I recommend to try C-h R info.

Here is the screenshot:

I think it's worth to try if you just want to play the song from minibuffer.

Please note that many users of FOSS are also developers or contributors. Who wants to report a bug or send a patch if the community is worse?

1. Gimp to batch edit pictures in a script (I know about ImageMagick but still)

It seems to exist: https://www.gimp.org/tutorials/Basic_Batch/

Bash should be fine. On typical Bash installation I think this will work (please try to understand each command line before you actually try):

$ cp ~/.bashrc ~/.bashrc.bak
$ cp ~/.bash_history ~/.bash_history.bak
$ printf 'set +o history' >> ~/.bashrc
$ printf "sudo apt update\nsudo apt upgrade\n" > .bash_history
$ (Press Ctrl+D to logout)

For the next bash session you can refer only the two commands from the history with Up/Down/C-p/C-n.

Long ago I made such restricted shell with filtering the shell command history file then disabling command history logging. With some shell scripting, I think you can get more sophisticated version. What shell are you using? (Bash, Fish, Zsh, etc.)
