Fedora Silverblue With Disk Encryption: How I Almost Lost Everything But Gained Much Wisdom (Side Story: Bmaptool And Ddrescue: Why One Should Never Ever Use Dd)

While testing different RADXA ROCK 5B board boot options, I inadvertently typed sudo dd of=/dev/nvme0n1 on my notebook! While recovering I learned one too many things which one supposedly should know when running a modern distro like Fedora Silverblue with disk encryption. This talk covers some lessons learned from using Fedora Silverblue as a daily driver and outlines what modifications might make sense during installation and what parts you might want to have backed up to avoid a similar disastrous shocking moment from happening. As a side story, I cover why using dd is a really bad idea and what better options to consider.
