QEMU is a generic and open source machine emulator and virtualizer.

This build is only for the user-mode static version of the binaries.

The primary use-case is to run alien achitecture (aarch64)
docker containers on x86_64.

This package installs all compatible qemu binfmt descriptions
into /usr/share/binfmts

If you have installed (and activated in /etc/rc.d/)
the binfmt-support service, they will be loaded at machine start up.

Then you should be able to run all compatible docker images through
qemu emulation transparently.

/*
modprobe binfmt_misc
mount -t binfmt_misc none /proc/sys/fs/binfmt_misc
update-binfmts --import
update-binfmts --enable

docker run --platform=linux/arm64 --rm  -it \
aclemons/slackware:current echo passed || echo failed
