HI Jone. What config did you use? I see you've been on the list for some time so I'm guessing your config contains more than the barebones or similar. A few things that may help, of the top of my head; without knowing more: Use a package manifest and trim down anything not strictly necessary from the packages in system config to the user manifest. Examples from my configuration - manifest: https://notabug.org/thomassgn/guixsd-configuration/src/master/usr-pkg-manifest.scm How I "install" it: https://notabug.org/thomassgn/guixsd-configuration/src/master/Makefile#L17 (this setup/makefile is currently fairly borked and buggy, but 'make p' currently works as intended) :-) Comment out anything else not necessary to get a basic system up and running in your system config, like services and others. I find it much more pleasant fiddling with "extras" when I have a mostly working system. Hope that helps. On Tue, 3 Jul 2018 03:37:54 +0000 Jone wrote: > Clean installation took many hours.
