According to docs this command to add ~arch keyword should work like this: $ flaggie "xfce-extra/xfce4-embed-plugin" '+~amd64' This does add the package but not the keyword leaving an invalid /etc/portage/package.accept_keywords/xall here. However adding arch keyword like this works fine: $ flaggie "xfce-extra/xfce4-embed-plugin" '+amd64' Reproducible: Always
Sry, I just found in man portage: Format: - lines without any KEYWORDS imply unstable host arch So this may be intended behaviour of flaggie, if so please set to INVALID.
Indeed, a line missing keyword syntax accepts unstable packages.
