Calling emerge with --configroot set, I still get: Autounmask changes successfully written. Would you like to add these changes to your config files? [Yes/No] * IMPORTANT: config file '/etc/portage/package.use/xtables-addons' needs updating. (we should also get rid of this let's-just-append-stuff-to-some-file logic) Reproducible: Always
Please post your emerge --info
If you also use --root, then /etc/portage is used for build-time dependencies from DEPEND. Did you use --root or ROOT?
