# Casper Casper is a technology or product recorded in [[Scanned_20260730-1706|Scanned_20260730-1706]]. In the reconstruction, Casper supports Ubuntu live boot, while Ubiquity was Ubuntu's graphical installer. ## Historical and Technical Context [[Bochs|Bochs]] is an x86 emulator; `video=bochs` or the Bochs display adapter appears in virtualized boot configurations. [[Citrix Hypervisor|Citrix XenServer]], [[Xen|Xen]], and `.xva` concern virtual-machine export/import. [[Ceph|Ceph]] is distributed storage. [[Casper|Casper]] supports Ubuntu live boot, while [[Ubiquity|Ubiquity]] was Ubuntu's graphical installer. ## Role in Scanned_20260730-1706 The page links boot configuration to enterprise virtualization and live-install tooling. It looks like a shortlist for making a portable image boot across emulated, Xen, PXE, and Ubuntu-live environments. ## Notebook Evidence - [[Scanned_20260730-1706|Scanned_20260730-1706]], PDF page 22: Boot and enterprise-platform shortlist. **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, Casper appears with [[Bochs|Bochs]], [[Ceph|Ceph]], [[Citrix Hypervisor|Citrix Hypervisor]], [[Ubiquity|Ubiquity]], [[Xen|Xen]]. These are page-level or reconstruction-level relationships, not automatic claims of dependency. ## Cross-Notebook Significance This entity expands the collection’s recurring vertical method: begin with a visible product, name, or interface; identify the hidden control layer; then connect it to recovery, authority, evidence, or continuity without assuming a relationship that the page does not prove. ## Missed Signals and Open Leads The exact `grub.cfg instead video-bochs` instruction is syntactically incomplete; locate the associated configuration file before interpreting it as a command. ## Sources - [[Scanned_20260730-1706|Scanned_20260730-1706]], especially PDF page(s) 22. - `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.
