This plain renders such a VM unusable even for testing. YMMV, but I call this in-acceptable and this is why I'm using a vm-image ("guix system vm-image =E2=80=A6", which is much faster: Plase start-up 2= 5 sec., Menu appears immediately. --=20 Regards Hartmut Goebel | Hartmut Goebel | h.goebel@crazy-compilers.com | | www.crazy-compilers.com | compilers which you thought are impossible |
