Implementations

impl KernelInfo

pub fn new(rootpath: &str, kver: &str) -> Result<Self, Error>

Creates an instance of a KernelInfo struct with the version of the kernel and paths to required points for module analysis.

Root path is either “/” for the host filesystem or a mountpoint to the root filesystem.

NOTE: The module resolver is very simple here and won’t scale that much if a kernel will have millions of modules. But as of 2024 it works OK with those dozen of thousands as for a generator. Generated CPIO anyway will contain already sorted list.

pub fn get_kernel_path(&self) -> PathBuf

Return current kernel info root path.

pub fn is_valid(&self) -> bool

Returns true if there are actual modules on the media for this kernel. There are often kernel paths left after a kernel was not completely purged.

pub fn get_dep_path(&self) -> &str

Get path of dependencies file

pub fn get_deps_for(&self, names: &[String]) -> HashMap<String, Vec<String>>

Resolve all module dependencies

pub fn is_dep(&self, name: &str) -> bool

Return true if a given module is a dependency to something else

pub fn get_deps_for_flatten(&self, names: &[String]) -> Vec<String>

Same as get_deps_for, except returns flattened list for all modules with their dependencies.

pub fn get_disk_modules(&self) -> Vec<String>

Get all found modules
