# Boot the Foundry OS image interactively on the pinned Rustbelt kernel:
# a QEMU window (or add NOGRAPHIC=1 for serial only), our image as disk 0
# (B:), the kernel's test disks as C:, D:, E:. Same devices as the kernel's
# `cargo run`. The hvc0 console is on the unix socket OUT/hvc0.sock:
#   socat - UNIX-CONNECT:out/hvc0.sock     (then `getty /dev/hvc0 &` in Foundry)
