I am trying to bootstrap and configure an embedded system. I need to enable certain systemd services (e.g. networkd, resolved).
I'm working on an x86* machine while the one that I'm configuring is an ARM machine - so I (presumably) need to use the host's systemd to edit the systemd configuration stored in the ARM's file system.
How would I do the equivalent actions which these do on the x86 host, in the offline ARM system which I have mounted?
systemctl enable foo.service systemctl disable foo.service
netctl enable <name> is still doable as
systemctl enable netctl@<name>.
