bootc-install-to-disk - Install to the target block device

SYNOPSIS

bootc install to-disk [--wipe] [--block-setup] [--filesystem] [--root-size] [--source-imgref] [--target-transport] [--target-imgref] [--enforce-container-sigpolicy] [--target-ostree-remote] [--skip-fetch-check] [--disable-selinux] [--karg] [--root-ssh-authorized-keys] [--generic-image] [--via-loopback] [-h|--help] <DEVICE>

DESCRIPTION

Install to the target block device.

This command must be invoked inside of the container, which will be installed. The container must be run in `--privileged` mode, and hence will be able to see all block devices on the system.

The default storage layout uses the root filesystem type configured in the container image, alongside any required system partitions such as the EFI system partition. Use `install to-filesystem` for anything more complex such as RAID, LVM, LUKS etc.

OPTIONS

--wipe

: Automatically wipe all existing data on device

--block-setup=BLOCK_SETUP

: Target root block device setup.

direct: Filesystem written directly to block device tpm2-luks: Bind unlock of filesystem to presence of the default tpm2 device.\

[*possible values: *direct, tpm2-luks]

--filesystem=FILESYSTEM

: Target root filesystem type\

[*possible values: *xfs, ext4, btrfs]

--root-size=ROOT_SIZE

: Size of the root partition (default specifier: M). Allowed specifiers: M (mebibytes), G (gibibytes), T (tebibytes).

By default, all remaining space on the disk will be used.

--source-imgref=SOURCE_IMGREF

: Install the system from an explicitly given source.

By default, bootc install and install-to-filesystem assumes that it runs in a podman container, and it takes the container image to install from the podmans container registry. If --source-imgref is given, bootc uses it as the installation source, instead of the behaviour explained in the previous paragraph. See skopeo(1) for accepted formats.

--target-transport=TARGET_TRANSPORT [default: registry]

: The transport; e.g. oci, oci-archive, containers-storage. Defaults to `registry`

--target-imgref=TARGET_IMGREF

: Specify the image to fetch for subsequent updates

--enforce-container-sigpolicy

: This is the inverse of the previous `--target-no-signature-verification` (which is now a no-op). Enabling this option enforces that `/etc/containers/policy.json` includes a default policy which requires signatures

--target-ostree-remote=TARGET_OSTREE_REMOTE

: Enable verification via an ostree remote

--skip-fetch-check

: By default, the accessiblity of the target image will be verified (just the manifest will be fetched). Specifying this option suppresses the check; use this when you know the issues it might find are addressed.

A common reason this may fail is when one is using an image which requires registry authentication, but not embedding the pull secret in the image so that updates can be fetched by the installed OS "day 2".

--disable-selinux

: Disable SELinux in the target (installed) system.

This is currently necessary to install *from* a system with SELinux disabled but where the target does have SELinux enabled.

--karg=KARG

: Add a kernel argument. This option can be provided multiple times.

Example: --karg=nosmt --karg=console=ttyS0,114800n8

--root-ssh-authorized-keys=ROOT_SSH_AUTHORIZED_KEYS

: The path to an `authorized_keys` that will be injected into the `root` account.

The implementation of this uses systemd `tmpfiles.d`, writing to a file named `/etc/tmpfiles.d/bootc-root-ssh.conf`. This will have the effect that by default, the SSH credentials will be set if not present. The intention behind this is to allow mounting the whole `/root` home directory as a `tmpfs`, while still getting the SSH key replaced on boot.

--generic-image

: Perform configuration changes suitable for a "generic" disk image. At the moment:

- All bootloader types will be installed - Changes to the system firmware will be skipped

--via-loopback

: Instead of targeting a block device, write to a file via loopback

-h, --help

: Print help (see a summary with -h)

<DEVICE>

: Target block device for installation. The entire device will be wiped
