- 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.
- Debian-based
- Family filter: Debian and derivatives (Ubuntu, Mint, Kali, Parrot, Tails, …).
- RHEL-based
- Family filter: Red Hat Enterprise Linux rebuilds/compatibles (Rocky, AlmaLinux, …).
- Pentest
- Penetration-testing oriented media (Kali, Parrot Security) for authorized assessments only.
- Amnesic
- Live system that leaves minimal forensic residue on host storage (e.g. Tails).
- Talos / talosctl
- Kubernetes-only immutable OS; nodes managed via the talosctl API (no SSH).
- Immutable
- Image-based OS with atomic updates and minimal mutable surface (Talos, Flatcar, FCOS, Kairos).
- Container OS
- Host OS optimized to run containers / Kubernetes rather than general desktop workloads.
- Lane
- Hub grouping: General · IT-Security & Privacy · Kubernetes & Immutable Node OS.
- Air-gap
- Network segment without general Internet egress. Media is introduced via controlled transfer (e.g. jumphost SCP).
- Jumphost / Bastion
- Hardened host that can reach both the public network (or mirror path) and the isolated segment; used to stage and push ISOs.
- ProxyJump
- SSH multi-hop (
-J) through a bastion to the final air-gapped host.
- Bundle
- Transfer package: ISO + checksum/digest file + optional GPG sig/keys + MANIFEST.txt.
