- LTS
- Long-Term Support release. Extended security maintenance window; preferred for production fleets.
- ISO
- Optical/disk image of an installer or live system. Usually hybrid (USB-writable) on modern distros.
- SHA256
- 256-bit cryptographic hash. Confirms file bit-identity; does not prove authenticity alone without signed checksums.
- SHA512
- 512-bit hash variant. Used by some projects (e.g. Debian, openSUSE Leap 16) alongside or instead of SHA256.
- GPG
- OpenPGP tooling for cryptographic signatures. Use to authenticate official checksum files from the project.
- Mirror
- Replica of official package/ISO content. This gateway is not a binary mirror — metadata only.
- Netinst
- Network installer image. Small local payload; packages fetched from online repositories during install.
- Verify
- Confirm a local ISO matches a published digest (and, ideally, that the digest file is GPG-authentic).
- Hybrid
- ISO constructed to boot from both optical media and USB mass storage without conversion.
- Rolling
- Continuously updated release model (Arch, Tumbleweed). No traditional “point” freeze for the base system.
- Stable
- Fixed-release train with controlled updates (Debian stable, Leap). Predictable for ops baselines.
- Gateway
- This service: curated links, hashes, status, and CLI — not a CDN for ISO bytes.
- Channel
- Logical feed identity for this site:
os.webservice.digital.
- osdl
- Operator Shell Download Link — the CLI bridge command installed from
/cli.
