bhatti update

Update bhatti to the latest release.

Synopsis

bhatti update                    # auto-detect: CLI on a client, full update on a server
sudo bhatti update               # full server update (CLI, kernel, lohar, rootfs)
sudo bhatti update --tiers all   # also pull additional rootfs tiers
bhatti update --cli-only         # update just the CLI binary, even on a server

Description

Downloads https://bhatti.sh/install and runs it. The installer auto-detects whether this is a server (config exists at /etc/bhatti/config.yaml) or a CLI-only host, and updates accordingly.

On a CLI-only machine: updates the bhatti binary at /usr/local/bin/bhatti. Doesn’t need root unless /usr/local/bin isn’t writable by the user.

On a server: updates everything — CLI, Firecracker, lohar, kernel, and any installed rootfs tier images. Only changed components are re-downloaded; unchanged tiers and kernels are skipped.

--cli-only forces the binary-only update path even on a server. Useful when you want to test a CLI fix without touching kernel/rootfs.

--tiers takes a comma-separated list (or all) of additional rootfs tiers to install (browser, docker, computer). The default install only ships minimal; this is how you add more without re-running the full install command.

Server updates require root (Firecracker and /var/lib/bhatti are root-owned). The command refuses up front if it detects a server install but the user isn’t root, rather than partly-completing then failing inside the install script.

Examples

# CLI host
bhatti update

# Server, default behaviour (full update)
sudo bhatti update

# Server, also pull all tiers
sudo bhatti update --tiers all

# Server, only update the CLI binary
bhatti update --cli-only

# Server, add a single tier
sudo bhatti update --tiers browser
