Just a note about
vscodium-1.77.1.23095.x86_64.xzm. Thanks for providing it of course.
This is not going to be a
portable installation. All the local setting, extensions, etc. are going to be saved in your changes (various places under /mnt/live/memory/changes etc.), and it will grow over 1GB!
The official Visual Studio Code allows a portable installation as per
https://code.visualstudio.com/docs/editor/portable :
download the latest .tar.gz, unzip, create the data subfolder, keep moving it when updating under a new installation folder and so on.
One may turn that installation into an easily portable .squashfs file -- No, that folder needs to be writable for vscode to run, so it has to live in an uncompressed state, around 1GB. But at least in one single folder without polluting your changes when using the system installation provided by the above .xzm module (thanks again, though)
