GNU GRUB - Bryant McGill

# GNU GRUB GNU GRUB is a technology or product recorded in [[Scanned_20260730-1706|Scanned_20260730-1706]]. In the reconstruction, grml-rescueboot integrates rescue ISO images into GRUB, allowing recovery media to be booted without first writing it to removable media. ## Historical and Technical Context [[rEFInd|rEFInd]] is a UEFI boot manager that presents operating-system choices at startup and can participate in network boot workflows ([rEFInd documentation](https://www.rodsbooks.com/refind/)). [[GRML Rescueboot|grml-rescueboot]] integrates rescue ISO images into [[GNU GRUB|GRUB]], allowing recovery media to be booted without first writing it to removable media. [[OpenNebula|OpenNebula]] is an open-source cloud and virtualization management platform spanning enterprise, private, hybrid, and edge infrastructure ([OpenNebula documentation](https://docs.opennebula.io/7.2/)). “LightMBP” likely names a lightweight MacBook Pro host; “NVMANnode” appears to be a local node name. ## Role in Scanned_20260730-1706 The page is designing a **rescue-capable multi-boot/cloud node**: keep ISO recovery media available in GRUB, consider rEFInd for UEFI selection, and associate the host with an OpenNebula-managed environment. ## Notebook Evidence - [[Scanned_20260730-1706|Scanned_20260730-1706]], PDF page 10: Boot managers and cloud node. **Evidentiary status:** The page occurrence and transcription are notebook evidence. Technical identification follows the source reconstruction’s cited research. Co-occurrence does not by itself prove ownership, deployment, or a direct operational relationship. ## Relationships and Overlays On the cited page or pages, GNU GRUB appears with [[GRML Rescueboot|GRML Rescueboot]], [[OpenNebula|OpenNebula]], [[rEFInd|rEFInd]]. These are page-level or reconstruction-level relationships, not automatic claims of dependency. ## Cross-Notebook Significance This note extends the recovery and boot-media concerns in [[Scanned_20260730-1802|Scanned_20260730-1802]], especially its Linux services, NFS, installer inventory, and bootable USB/UEFI pages. The new notebook turns those components into a reversible acquisition and recovery workflow. ## Missed Signals and Open Leads “CI” may mean cloud infrastructure, continuous integration, or a local project label. “inode fs?” is too fragmentary to resolve. ## Sources - [[Scanned_20260730-1706|Scanned_20260730-1706]], especially PDF page(s) 10. - `Scanned_20260730-1706.pdf`, cited as a plain archival filename; the PDF is not linked from `wiki-notes`. - External research citations used for identification remain preserved in the source reconstruction. - [rEFInd documentation](https://www.rodsbooks.com/refind/) - [OpenNebula documentation](https://docs.opennebula.io/7.2/) ## Scanned_20260730-1719 overlay **Source evidence:** [[Scanned_20260730-1719#PDF page 29 — Coreboot, Pop!_OS, Go, IPFS, CERN, and boot research questions|page 29]], [[Scanned_20260730-1719#PDF page 54 — Windows system inventory, firmware shortcuts, GRUB, and partitioning|page 54]], [[Scanned_20260730-1719#PDF page 60 — Shells, startup mute, kernel-image lineage, boot loaders, and archives|page 60]], [[Scanned_20260730-1719#PDF page 66 — Ubuntu installer, Macbuntu, MOK errors, Compiz, GRUB, Xen, and ACPI|page 66]], [[Scanned_20260730-1719#PDF page 68 — Environment variables, ISO hybrid boot, GRUB, extlinux, and AUFS|page 68]], [[Scanned_20260730-1719#PDF page 73 — Leah Rowe, Minifree, Libreboot, osboot, and “federation”|page 73]], [[Scanned_20260730-1719#PDF page 75 — Coreboot/Libreboot summary and supported operating systems|page 75]]. [[Go programming language|Go]], [[InterPlanetary File System|IPFS]], [[Tor|Tor]], and [[CERN|CERN]] represent distributed services, anonymity, and research infrastructure. [[GNU GRUB|GRUB 2]] is a boot loader; live media and utility partitions preserve recovery paths outside the installed OS. **Relationship overlay:** [[AUFS|AUFS]] · [[CERN|CERN]] · [[cfdisk|cfdisk]] · [[CompizConfig Settings Manager|CompizConfig Settings Manager]] · [[EXTLINUX|EXTLINUX]] · [[Go programming language|Go programming language]] · [[Internet Archive|Internet Archive]] · [[InterPlanetary File System|InterPlanetary File System]] · [[Libreboot|Libreboot]] · [[LILO|LILO]] · [[Linux Kernel Archives|Linux Kernel Archives]] · [[LZO|LZO]].
