Hello, for testing I used to build VM using "guix system vm …" and the machines are, well, reacting slowly: Plasma start up: 80 sec. Menu: 36 sec When I tried a Vm created with "guix system vm-image …" the machine is much quicker: Plasma start up:  25 sec. Menu: immediately. This is a huge contrast, so I wonder what is the reason for this. Any ideas? And any ideas how to speed up the first variant? -- Regards Hartmut Goebel | Hartmut Goebel | h.goebel@crazy-compilers.com | | www.crazy-compilers.com | compilers which you thought are impossible |
