Reduce systemd spam to console with netctl service messages?

I use the console to login and for some work. Just recently install Arch on a Chromebook. I am getting lots of systemd log spam to the console, from what appears to be netctl service trying to find wireless. Is there any way to reduce the log level output to the console?

Any help appreciated.

You could try not using netctl.
If you have /etc/wpa_supplicant/wpa_supplicant.conf set up correctly, dhcpcd.service runs a hook (/usr/lib/dhcpcd-hooks/10-wpa_supplicant) for wpa_supplicant which should bring your connection up wihout any other services running.
See man 8 dhcpcd-run-hooks

Yes, that is an option but I'd like to keep the netctl service to enable a number of different wifi connections and to auto-connect to them.

wpa_supplicant will do all that. It's what netctl and other network managers use underneath anyway. And if your network needs are fairly simple, check out systemd-networkd instead of dhcpcd. Don't forget about resolved and timesyncd too!

Kill all the bloat!!!

Guys, please read the original question; nobody cares which tools _you_ use. Also, answering "get rid of netctl" is just stupid.

@lagagnon:
Are you sure that the messages are from systemd and not kernel? Can you show  an example? Also, what's the content of your /proc/sys/kernel/printk?

A really simple work around would be to flip over to tty2 and log in there. 
Another might be to configure journald to use a different console.
