The system no longer fails to terminate with `/usr` on *iSCSI* or *NFS*
In previous versions of Red Hat Enterprise Linux 7, the termination of the system sometimes failed and the system remained hung if the `/usr` folder was mounted over a network (e.g. *NFS* or *iSCSI*). This issue has been resolved, and the system should now shut down normally.
+++ This bug was initially created as a clone of Bug #1369790 +++
Description of problem:
There are errors when shutting down a system with /usr on iSCSI (/boot, / and swap are on a local disk):
[root@localhost ~]# lsblk

Version-Release number of selected component (if applicable):
RHEL-7.3 Beta (anaconda-184.108.40.206-1.el7, systemd-219-26.el7, dracut-033-453.el7)
Steps to Reproduce:
1. Install a system with /usr on iSCSI and /boot, / and swap stored on a local disk
2. try to reboot the installed system
error messages, connection timeout, system doesn't reboot
system reboots without errors, all file systems are unmounted cleanly
This bug blocks initscripts BZ #1369790. We are using this code to test if the root or /usr is located on network block device:
> systemctl show --property=RequiredBy -- -.mount usr.mount | grep -q 'remote-fs.target'
It is expected that the output of command above will contain 'remote-fs.target'. However, currently for /usr located on network block device it shows this:
(This issue has been more discussed on github here:
Dracut only mounts /usr by itself when there is no systemd present. Otherwise this is don in fstab generator.
