How to mold a LiveUsb assembly of Linux?

Question

linux

Good day.
I didn't do it before, but now it's very necessary.
You need to build your Linux Live Usb assembly with a certain set of applications and their settings.
I know that there are a lot of manuals on the Internet on this topic, but I'm not a Linux user. I am familiar with Linux at the level of "correct configs, install the application through the terminal". I worked with Linux (debian, ubuntu), but not enough to understand all the aspects that the authors of the articles do not really cover (apparently, the articles are designed for Linux users).
A scheme is spinning in my head - sketch out everything you need in a virtual machine, apply all the necessary settings, hone everything as needed and somehow pack it into an iso image with the ability to Live boot.
I would be very grateful if someone could suggest a working method suitable for my needs.
I am very tired of experiments with endless downloads of distributions and errors and conflicts of library versions during the manipulations described in the articles (especially when the work is done by 80%, and at the end an error with a conflict crashes).
Hope for understanding.

Answer 1

If without "special understanding", then I'm afraid there are no solutions. Hence, "tired of experimenting with endless downloads of distributions and errors and conflicts of library versions during manipulations." It will be easier to sit down at once, read mana, and first experiment in a virtual machine. If you're bad, then take VirtualBox. If you rummage a little better, then VMware will help you. I speak as a tench user with a certain experience.
If you want to build your distro, then LFS book will help you. If you can't do it - well, then it's not yours.

Answer 3

The desired livecd distribution is taken as a basis.
It is mounted in / media / cdrom for example, then the * .squashfs file is located (here the "live" OS is located).
It is copied to a working folder, for example /mnt/ (otherwise it will not be possible to make changes later)
Next is the instruction on how to work with squashfs images (unpack, enroll, deliver/delete/configure what is needed, pack back into squashfs).
We replace the original squashfs image from the distribution with our own and build iso.
Then we enjoy life and use Livecd with our favorite programs

Answer 5

Have you already gone to Google and looked in the repositories, but blindness did not make it possible to see the bootcd package in the Debian / Ubuntu turnips, which says “run your system from cd without need for disks” right in the description?
