Rollback misconfigured network settings in systemd using etckeeper?

I was thinking how to automatically rollback network misconfigurations with etckeeper and systemd. Workflow: # etckeeper commit # $EDITOR /etc/systemd/network/wired.network # systemctl restart systemd-networkd You broke the network! I'm calling your mom! Here's your broken config: $(cat broken_file) $(etckeeper vcs reset -- old_config_file) # $EDITOR /etc/systemd/network/wired.network # systemctl restart systemd-networkd # Currently i'm stuck how to hook into restart event. gdbus monitor --system --dest org.freedesktop --object-path /org/freedesktop Doesn't output anything when running # systemctl restart systemd-networkd Script itself could be something like: * hook into systemd restart and if possible, directly into restart systemd-networkd * Read the hook information if it contains that restart failed, otherwise read systemctl is-active systemd-networkd * Rename broken file to $file.broken * Restore: etckeeper vcs reset -- $file * systemctl stop automatic-net-configuration-rollback.service (so that there's no infinite loop) * systemctl restart systemd-networkd * Works -> systemctl start automatic-net-configuration-rollback.service * Doesn't -> echo Rollbacked config file doesn't work either. Repair manually and start automatic rollback after it works. Is this possible and/or does systemd already have this kind of service built-in or has someone made one already? My google searches came up empty.
