Думаю, шо после недавнего треда про SecureBoot будет неплохо напомнить ссылку на петицию FSF относительно отключабельности SecureBoot для тех, хто не подписал или забыл.
Цитата:
We, the undersigned, urge all computer makers implementing UEFI's so-called «Secure Boot» to do it in a way that allows free software operating systems to be installed. To respect user freedom and truly protect user security, manufacturers must either allow computer owners to disable the boot restrictions, or provide a sure-fire way for them to install and run a free software operating system of their choice. We commit that we will neither purchase nor recommend computers that strip users of this critical freedom, and we will actively urge people in our communities to avoid such jailed systems.
