rpc-statd fails to start, during boot as a result NFSv3 shares fail to mount.

Issue

A NFSv3 share fails to mount at boot time, if rpc-statd fails to start. Usually, this would be expected, considering mounting a NFSv3 share with locking (default), would require rpc-statd to be in running state.

The service status shows that it failed to start, since the operation had timed out:

 * rpc-statd.service - NFS status monitor for NFSv2/3 locking.
    Loaded: loaded (/usr/lib/systemd/system/rpc-statd.service; static; vendor preset: disabled)
    Active: failed (Result: timeout) since Mon 2022-10-24 08:38:31 GMT; 3min 15s ago

If shares are mounted with nolock, mount operation doesn't fail as expected, however rpc-mountd fails to start with timeout, in place of rpc-statd:
