Terms used in these guides
- ISO and live session
- An ISO is the image used to create the boot media. The live session runs the system from that media before installation.
- UEFI and Secure Boot
- UEFI is the firmware used in the documented boot flow. Secure Boot verifies the signatures of boot components according to the firmware's trust configuration.
- RPM and Zypper
- RPM is the system's package format. Zypper manages these packages and their repositories.
- Flatpak
- An app distribution format and tool with its own repositories and runtimes.
- Snapshot and backup
- A snapshot records a state of the file system. A backup is a copy of the data for recovery; an independent copy also protects against failure of the original disk.
- SHA-256 checksum
- A value used to check whether a file matches the expected content. It must be obtained from the release that corresponds to the image.
