Hi! Please test the USB installation image at: http://www.fdn.fr/~lcourtes/software/guix/guixsd-usb-install-0.9.0pre.x86_64-linux.xz SHA1: 0d7f37d5b18f7b4437b447fc8a90b44c470f6e99 http://www.fdn.fr/~lcourtes/software/guix/guixsd-usb-install-0.9.0pre.x86_64-linux.xz.sig This is for x86_64 and the installation instruction still apply: https://www.gnu.org/software/guix/manual/html_node/System-Installation.html … but tty2 in the installation image provides the latest version of the manual, with slightly different examples (notably with an encrypted root partition.) I’m sorry that once again these arrive a day or two before the target release date. Please report back ASAP. Reports of installations in VMs are interesting; bare-metal installation are even better. Thanks! :-) Ludo’.
