Reproducible XFS Filesystems - Populating Images Without Mounting
UA2.114 (Baudoux) | Day 2 | 10:40 - 11:00 | Speakers: Luca Di Maio
Abstract
Creating filesystem images typically requires mounting, copying files, and hoping your build environment doesn't introduce non-determinism. New capabilities in mkfs.xfs solve both problems. You can now populate an XFS filesystem directly from a directory tree at creation time, no mount required. I'll cover the implementation approach, discuss design, and show how to use it. Useful for distributions, embedded systems, and anyone who needs verifiable filesystem artifacts.
