Functions

func CheckDirectoryCustomizationsPolicy 

func CheckDirectoryCustomizationsPolicy(dirs []DirectoryCustomization, pathPolicy *pathpolicy.PathPolicies) error

CheckDirectoryCustomizationsPolicy checks if the given Directory customizations are allowed by the path policy. If any of the customizations are not allowed by the path policy, an error is returned. Otherwise, nil is returned.

func CheckFileCustomizationsPolicy 

func CheckFileCustomizationsPolicy(files []FileCustomization, pathPolicy *pathpolicy.PathPolicies) error

CheckFileCustomizationsPolicy checks if the given File customizations are allowed by the path policy. If any of the customizations are not allowed by the path policy, an error is returned. Otherwise, nil is returned.

func CheckMountpointsPolicy 

func CheckMountpointsPolicy(mountpoints []FilesystemCustomization, mountpointAllowList *pathpolicy.PathPolicies) error

CheckMountpointsPolicy checks if the mountpoints are allowed by the policy

func DirectoryCustomizationsToFsNodeDirectories 

func DirectoryCustomizationsToFsNodeDirectories(dirs []DirectoryCustomization) ([]*fsnode.Directory, error)

DirectoryCustomizationsToFsNodeDirectories converts a slice of DirectoryCustomizations to a slice of fsnode.Directories

func FileCustomizationsToFsNodeFiles 

func FileCustomizationsToFsNodeFiles(files []FileCustomization) ([]*fsnode.File, error)
