CARINA Core is the foundation layer of CARINA OS. It converts a standard Ubuntu Server installation into CARINA OS by applying identity branding, installing the CLI, configuring security defaults, and enabling the profile system.
Standard Ubuntu Server installation. CARINA does not modify the kernel or core system libraries.
Replaces Ubuntu branding with CARINA identity:
/etc/os-release — Identifies as CARINA OS/etc/motd — Clean, professional login messageNAME="CARINA OS"
PRETTY_NAME="CARINA OS (Core)"
ID=carina
ID_LIKE=debian
VERSION_ID="0.1"
System management tool at /usr/local/bin/carina providing health checks, profile management, and GUI toggling.
Collections of packages and configuration scripts. See FlightDeck and MissionLab.
Systemd-based first-boot configuration via /etc/carina/firstboot.yaml:
/etc/carina/ — Configuration files
/opt/carina/ — Tools and profiles
/var/log/carina/ — Log files
/usr/local/bin/carina — CLI binary
The Core profile applies:
carina doctor # Check all system components
carina version # Verify version
