ZFS Software ECC Dynamic Toggle

Context-aware memory verification for non-ECC RAM. Fail-loud design.

🖧 Automated toggle for zfs_flags=0x10 (ZFS_DEBUG_MODIFY). Enables in-memory data verification on non-ECC RAM during idle/server tasks to prevent silent corruption, and disables it during gaming (Steam) to maximize performance. Implements the mitigation strategy recommended by Matthew Ahrens for non-ECC systems.

Fedora Root-on-ZFS: UKI + Secure Boot with NVIDIA (Bypassing Broken MOKUTIL on Modern UEFI)

⚠️ DISCLAIMER & ATTRIBUTION

Base Installation: This guide assumes a successful base installation using Gregory Lee's excellent fedora-on-zfs script. All credit for the foundational installation logic belongs to them.

Unofficial Workaround: The steps below for UKI integration, Secure Boot key enrollment, and MOKUTIL bypass are an unofficial community contribution.

• Not Affiliated: This guide is not endorsed by the OpenZFS project or Gregory Lee.
• Use at Your Own Risk: Modifying Secure Boot keys and kernel images can render your system unbootable. Always backup your data and EFI partition before proceeding.
• Hardware Specifics: Tested on ASRock B450M-HDV R4.0 (BIOS vP10.43). Behavior may vary on other UEFI implementations.

⚡ Update: Automated Solution Available

An automated, fully tested script is now available that removes all manual steps.
See: https://github.com/TheAlmightyOgreLord/openzfs-kernel-7.1-builder

It is agnostic, meaning it works on systems without Secure Boot as well as those with Secure Boot/UKI enabled.
