I'm the author of https://gentoo.duxsco.de/ which is a #gentoo installation guide supporting #secureboot, #measuredboot, #luks #encryption, #raid, a #SystemRescue based rescue partition with custom "chroot.sh", Gentoo hardened and (optional) #selinux.
This is my first post on Mastodon about this guide, as I've just finished chapter "15. Rescue System Upgrade" (https://gentoo.duxsco.de/rescue_system_upgrade/) which brings the guide to a more or less feature complete state on the x86_64 architecture.
I'd love to adapt my guide for #ARM, though. To make this happen, I need you to upvote the issue "Feature Request: system-rescue for ARM64" (https://gitlab.com/systemrescue/systemrescue-sources/-/issues/369). Please, support me here if you are interested in my project or if you just wish for SystemRescue to support #ARM64 in general. Thanks!
