SYNOPSIS

steamos-finalize-install [OPTIONS]

steamos-finalize-install completes a SteamOS installation by setting up bootloaders, installing the kernel, and applying system updates. It performs necessary migration steps to transition from an incomplete installation to a fully bootable system.
This command is typically run as part of the installation process but can be manually invoked to repair or reconfigure boot components.

PARAMETERS

--no-bootloaders

Skip bootloader setup

--no-kernel

Skip kernel installation

--no-migrate

Skip all migration steps

--roothash HASH

Set specific root hash during finalization

--force

CAVEATS

Requires root privileges. Incorrect use may render the system unbootable. The --force flag should be used with caution as it bypasses safety checks.
