I have used =E2=80=99-RR=E2=80=99 but because it is not working, then I tri= ed to install extra stuff in case. But if the kernel is not supporting the namespace, that=E2=80=99s a end. Period. > But wait, if you=E2=80=99re root, you can just as well upgrade to a kerne= l that > supports unprivileged user namespaces=E2=80=A6 or even install Guix? :-) That=E2=80=99s not so simple. It is an old RHEL and I am not sure that the upgrading path is smooth=E2=80=A6 So I am applying the well-known rule: do= not fix it if it is not broken. ;-) Well, I do not want to spend hours to figure out what is wrong with the new configuration (hardware). Installing Guix (the package manager) cannot work because the same problem: kernel. I am configuring another machine (Dell T620) to smooth the switch. But I hit the very same problem: spending hours to figure out what=E2=80=99s wr= ong because I am missing obscure hardware configurations. Thank you for your help. Cheers, simon
