Hello, after a reboot on a running remote host (it was running since several guix system generations ago... but with no reboots meanwhile) I get a failing networking service and consequently the ssh service (et al) refuses to start :-( Sorry I've no text to show you but a screenshot (see attachment below) because I'm connecting with a remote KVM console appliance. The networking service is failing with this message (manually copied here, please forgive mistakes): --8<---------------cut here---------------start------------->8--- [...] 11:28 vmunix [...] shepherd [1]: Exception caught while starting networking: (no-such-device "swws-bridge") shepherd [1]: Exception caught while staring networking. (%exception #<&netlink-response-error errno: 17>) --8<---------------cut here---------------end--------------->8--- The strange thing is that all the configured interfaces: eno1 Please find below the relevant parts of the configuration of my host. As you can see I've installed a libvirt daemon service (it is working) with an autostarted (by libvirt) bridge interface named "swws-bridge": I've tried stopping that bridge (virsh net-destroy...) but the networking service keeps failing after a "herd restart networking" --8<---------------cut here---------------start------------->8--- ;; ------------------------------------ ;; operating-system (operating-system (locale "en_US.utf8") (timezone "Europe/Rome") (keyboard-layout (keyboard-layout "us")) (host-name "ane") [...] (services (append (modify-services %base-services ;; base-services with modificatios (sysctl-service-type config => (sysctl-configuration (settings (append '(("net.ipv4.ip_forward" .
