[Solved] Network Mount Not Waiting for Network

My CIFS mount does not wait for the network to come online. I've set requires and after statements on my mount config, but it's not being respected.
Note the mount generally works. For example, if i start it manually (systemctl start srv-repository.mount) it mounts without issue.

/etc/systemd/system/srv-repository.mount

[Unit]
Description=repository
Requires=network-online.target systemd-networkd-wait-online.service
After=network-online.target systemd-networkd-wait-online.service

[Mount]
What=//10.0.0.10/repository
Where=/srv/repository
Options=users,username=USER,password=PASS,gid=users,uid=MyUser,iocharset=utf8,noauto,rw
Type=cifs
TimeoutSec=30

[Install]
WantedBy=multi-user.target

systemctl output.... the mount executes exactly when the wait completes, but the mount errors out on the network not being ready.

Re: [Solved] Network Mount Not Waiting for Network

systemctl status systemd-networkd
systemctl list-unit-files --state=enabled

Are you on the same subnet?

Yes, in the same subnet. My ip is 10.0.0.42/24.

Re: [Solved] Network Mount Not Waiting for Network

dhcpcd.service                        enabled
systemd-networkd.service              enabled

You've two network managing services enabled what is gonna cause some mess in any event. Probably dhcp interferes and the network is briefly down after being initially online (and at this point your mount fails)

Re: [Solved] Network Mount Not Waiting for Network

Thanks! I disabled dhcpcd.service, setup a DHCP config for networkd, and it works now.
