[Bug 1807749] [NEW] NFS V4 does not mount at system start

[imker]

Public bug reported:

Hi,

i'm running a view Ubuntu 18.10 Clients on a Ubuntu 18.04 NFS V4 Server.
I'm using Kerberos for user authentication and LDAP for user and group
synchronisation.

The shares are added to the /etc/fstab on my clients and they should be mounted automatically at system boot. Here is an example line from fstab:
nfs.server:/users         /home             	nfs4    sec=krb5i,soft,_netdev,auto  0  0

But after the system has booted and the Login-Screen appears the nfs
shares are not mounted on the client. Attached to this bug, you can find
an export of my journald entries from my last boot.

When I read this log carefully I find the following start order of relevant services:
Begin start nss_ldap (from line 822 on)
Begin start NetworkManager (from line 1198) 
Get IP from DHCP (line 2542)
NetworkManager Online (line 2551)
Try to mount NFS Shares (from line 2253)
nss_ldap connected (line 2761)

As far as I understand my setup, I do not have DNS before nss_ldap is
started. But since mounting the NFS shares needs DNS, the NFS mount
sequence should start after nss_ldap is fully started.

Thanks for your help
