Recently, I've been wanting to make a custom live iso with a couple of tools that I need but I really don't know where to start or what to do… any help?
E: I didn't phrase my post correctly, I need a portable set of desktop tools for development, running on the gnome desktop
Just a thought, but live systems are usually just a packed fs like squashfs in an iso with syslinux. Loop mount your image, copy the files out, start a chroot to use a package manager if you want, pack up the modified system back into squashfs, copy to the iso, run syslinux if you need to change the config, aaand your image is now modified 😹 a lot easier said than done, but maybe an interesting excursion.
