Crossdev questions.

I'm planning on building a cross-dev overlay arm64 to x86-64 to use for the fex chroot.
Is there a way to add an overlay to the crossdev tree?

What do you mean? As far as I know, cross-emerge changes PORTAGE_CONFIGROOT, so you might have to add additional repositories to /usr/<target>/etc/portage/repos.conf instead of /etc/portage/repos.conf, but other than that, it should work identically to any other portage configuration.

Ah, okay because the wiki made it seem the crossdev tree was added to the system's tree as a overlay.

Also would you know how to force crossdev to build multi-lib from the start? I can't seem to find the option.
