nfs mounts fail at boot if bind is running....

[Ed Greshko]

I suppose this is more of an FYI until I can determine where the bugzilla goes.....

If you use a "hostname" in your fstab for nfs mounts and your system is running bind and the resolv.conf is set to 127.0.0.1 the nfs mounts will fail at boot time.  This is true even if you have NetworkManager-wait-online enabled and an entry for the host in the hosts file.

Examining the journal shows that the mount attempt happens prior to named getting started, obviously.  :-)

Sort of leaning towards a systemd bugzilla

Does NetworkManager-wait-online actually still work in F19+? I have 
similar issues with autofs (ie IPA not available when autofs starts) and 
setting this in F18 and earlier solved the problem. Makes no difference 
in F19+.

Would having nm.service start earlier help?

Maybe a custom file?
-------------------------------------
.include /usr/lib/systemd/system/NetworkManager.service
[Unit]
Before=nfs whatever # I don't use nfs currently,

save as /etc/systemd/system/NetworkManager.service

Actually I decided to have a another look and it's a bit more 
complicated than I first thought. Autofs is starting up after
NetworkManager-wait-online but the problem was also that gdm doesn't. 
This means after boot up on this box, I can login before the network is 
fully ready which means I don't get a kerberos ticket and I'm unable to 
access NFS mounts etc. I suspect the reason why I never hit the gdm 
issue before was because I wasn't using a fast SSD, so the simple time 
it took to load X and GDM meant the network just happened to be ready by 
then. So the complete fix for me was to:

systemctl disable NetworkManager-wait-online
systemctl disable autofs
systemctl disable gdm

cp -a 
/usr/lib/systemd/system/{autofs.service,NetworkManager-wait-online.service,gdm.service} 
/etc/systemd/system/

Edit /etc/systemd/system/NetworkManager-wait-online.service and set:
ExecStart=/usr/bin/nm-online -q --timeout=180

Edit /etc/systemd/system/autofs.service and set:
After=network.target ypbind.service sssd.service 
NetworkManager-wait-online.service

Edit /etc/systemd/system/gdm.service and set:
After=systemd-user-sessions.service [e-mail] 
plymouth-quit.service NetworkManager-wait-online.service

systemctl daemon-reload
systemctl enable NetworkManager-wait-online
systemctl enable autofs
systemctl enable gdm
