I guess I was not clear... After adding a bg mount to fstab and
reboot, mounting a server that is not up, there is a mount in
background that looks like
# ps ax | grep mount
1104 ? Ss 0:00 /sbin/mount.nfs nfssrv:/home/tmp /mnt/tmp -o rw,bg
Looking at the remote-fs.target status:
# systemctl status remote-fs.target
* remote-fs.target - Remote File Systems
Loaded: loaded (/usr/lib/systemd/system/remote-fs.target; enabled; vendor
preset: enabled)

It appears to be successful
steved.
