For 'people should say just use iamroot' framing, the install gate is the single biggest discoverability bottleneck. This commit makes it: curl -sSL https://github.com/KaraZajac/IAMROOT/releases/latest/download/install.sh | sh .github/workflows/release.yml: - Triggers on semver tag push (v*.*.*) + manual dispatch. - Matrix build for x86_64 (gcc) and arm64 (aarch64-linux-gnu-gcc cross). - Per-arch sha256sum alongside the binary. - Auto-generates release notes pointing at CVES.md / ROADMAP.md and including the install one-liner with the version-specific URL. - Publishes via softprops/action-gh-release@v2. install.sh (also uploaded as a release artifact, so the curl|sh above is stable): - Detects arch (x86_64 / aarch64 → arm64). - Pulls iamroot-<arch> + iamroot-<arch>.sha256 from the requested version (default: latest). - Verifies sha256 via sha256sum or shasum -a 256. - Installs to /usr/local/bin/iamroot (or $IAMROOT_PREFIX). Uses sudo iff /usr/local/bin isn't already writable. - Prints quickstart hints + ethics pointer at the end. - Env knobs: IAMROOT_VERSION, IAMROOT_PREFIX, IAMROOT_REPO. README.md gains a 'Quickstart' section at the top with the four canonical commands: install, --scan, --audit, --detect-rules, fleet-scan. Lands the 'curl|bash and go' UX as the first thing visitors see.

# IAMROOT one-shot installer.
|
|
#
|
|
# Usage:
|
|
# curl -sSL https://github.com/KaraZajac/IAMROOT/releases/latest/download/install.sh | sh
|
|
#
|
|
# Or with explicit version:
|
|
# IAMROOT_VERSION=v0.1.0 curl ... | sh
|
|
#
|
|
# Or install to a different prefix:
|
|
# IAMROOT_PREFIX=$HOME/.local/bin curl ... | sh
|
|
#
|
|
# Environment:
|
|
# IAMROOT_VERSION release tag (default: latest)
|
|
# IAMROOT_PREFIX install dir (default: /usr/local/bin if writable, else error)
|
|
# IAMROOT_REPO override repo (default: KaraZajac/IAMROOT)
|
|
#
|
|
# Exit codes:
|
|
# 0 — installed successfully
|
|
# 1 — error (unsupported arch, download failure, permission denied)
