NAME

bootc-install-config.toml

DESCRIPTION

The bootc install process supports some basic customization. This configuration file is in TOML format, and will be discovered by the installation process in via "drop-in" files in /usr/lib/bootc/install that are processed in alphanumerical order.

The individual files are merged into a single final installation config, so it is supported for e.g. a container base image to provide a default root filesystem type, that can be overridden in a derived container image.

install

This is the only defined toplevel table.

The install section supports two subfields:

block: An array of supported to-disk backends enabled by this base container image; if not specified, this will just be direct. The only other supported value is tpm2-luks. The first value specified will be the default. To enable both, use block = ["direct", "tpm2-luks"].
filesystem: See below.
kargs: An array of strings; this will be appended to the set of kernel arguments.
match_architectures: An array of strings; this filters the install config.

filesystem

There is one valid field:

root: An instance of "filesystem-root"; see below

filesystem-root

There is one valid field:

type: This can be any basic Linux filesystem with a mkfs.$fstype. For example, ext4, xfs, etc.

Examples

[install.filesystem.root]
type = "xfs"
[install]
kargs = ["nosmt", "console=tty0"]
