Probably you are missing CONFIG_CGROUPS in your kernel configuration.
Please read README file in the systemd sources folder - it describes all options
required to be enabled in kernel configuration.

> [2] I would like also to include networkctl service (should I do something specific to

Please add following to your conf/local.conf file:
PACKAGECONFIG_append_pn-systemd = " networkd"
