Runs great. For the sake of experiment I am thinking of planting a QEMU emulation of a RISC-V instance on that very idle server. First I create a group : pluto# pw groupadd -n riscv -g 14142=20 Then add a user : pluto# adduser Username: riscv Full name: qemu rv64imafdc Uid (Leave empty for default): 14142 Login group [riscv]:=20 Login group is riscv. Invite riscv into other groups?
