It works rather well and is easy. This means we can just bootstrap from an existing /gnu tree in thu USB distribution provided the kernel/arch is compatible. At build time 'guix package -i guix' complained it did not have enough builders. The guix-daemon did not honour the -M 8 switch, so I had to add 30 build users on a 32 core machine. Now it is happy.
