For Reproducible Builds testing of armhf packages I run several machines
(some physical, some virtual) with arm64 kernel and armhf userland, and
it basically works.

It is a little tricky to set up multi-arch to be able to get the
linux-image-arm64 kernel from arm64 without pulling in all the
recommends on various :arm64 packages, but once it is set up, it works

I have no idea how difficult it would be to add multi-arch support to
debian-installer, but it is not too hard to build an image using
"mmdebstrap" that supports a linux-image-arm64:arm64 kernel on an armhf

live well,
