Debian packaging via cargo-deb:
- Add [package.metadata.deb] to Cargo.toml with assets, dependencies,
and conffiles declarations
- Maintainer scripts: postinst (create fips group, enable services,
restart on upgrade), prerm (stop/disable on remove, stop-only on
upgrade), postrm (purge config, keys, group)
- Systemd units (fips.service, fips-dns.service) with /usr/bin/ paths
for .deb installs
- tmpfiles.d entry for /run/fips/ runtime directory
- build-deb.sh wrapper script for building packages
README rewrite:
- Replace run-from-source Quick Start with Building section
- Add Installation options: Debian .deb (cargo-deb) and generic Linux
(systemd tarball)
- Add full Configuration reference with default fips.yaml
- Add Usage sections: DNS resolution, monitoring (fipsctl + fipstop),
service management, and testing
- Update project structure and features list
