I have installed Ubuntu on a 32GB USB and set it up like I want, Installing some programs and removing others. I have added custom wallpaper and splash screen.
How can I duplicate my modified OS and GMail it using Google Drive, (10GB limit), to friends and family for Christmas?
It should be able to run on any modern x86-64 computer that meets Ubuntu hardware specifications. It should be installable using Rufus, Etcher, mkusb and Gnome-Disks. I would also like to be able to install it from a USB stick.
I have heard of and tried Remastersys, ISORespin, Ubuntu Customization Kit and Systemback, but these all seem to be abandoned now.
Sometimes I work in VirtualBox and would like to be able to distribute the OS's I create there also.
