There is a folder(metadata/glsa) storing glsa information in Gentoo's portage, but funtoo's portage tree doesn't have this.

When execute glsa-check in funtoo, I get the error message with "ERROR: GLSA_DIR /usr/portage/metadata/glsa/ doesn't exist. Please fix this."

The following links are Gentoo's portage and Funtoo's portage in metadata.
