I=E2=80=99ll trace to investigate further when I can access it. In the meantime, could you try the following config, which disables logging on tty12, to see if it boots quicker? The config changes is twofold; first, after the =E2=80=98use-modules=E2=80=99 form of your OS con= fig, add: --8<---------------cut here---------------start------------->8--- (define %syslog.conf ;; Custom syslog.conf without /dev/tty12 logging. (plain-file "custom-syslog.conf" (let loop ((lines (string-split (plain-file-content %default-= syslog.conf) #\newline)) (result '())) (match lines (() (string-join (reverse result) "\n")) ((head . tail) (if (string-contains head "/dev/tty12") (loop tail result) ;drop this line (loop tail (cons head result)))))))) --8<---------------cut here---------------end--------------->8--- Second, in the =E2=80=98services=E2=80=99 field of your config, replace =E2=80=98%desktop-services=E2=80=99 with: --8<---------------cut here---------------start------------->8--- (modify-services %desktop-services (syslog-service-type _ =3D> (syslog-configuration (config-file %syslog.conf)))) --8<---------------cut here---------------end--------------->8--- Dunno if it=E2=80=99s silly, but at least it=E2=80=99ll allow us to check w= hether it=E2=80=99s just the framebuffer that=E2=80=99s slowing things down or if it=E2=80=99s = something else. Thanks for your help! Ludo=E2=80=99.
