Description of problem:
When booting from installation ISO image, there are two "[FAILED]" messages and after clean installation, the problem persists (visible with every boot).

Version-Release number of selected component (if applicable):
# rpm -qa systemd\*
systemd-207-7.el7.x86_64
systemd-sysv-207-7.el7.x86_64
systemd-libs-207-7.el7.x86_64


How reproducible:
I haven't tried installing it more than once, but it happens 100% of starts.

Steps to Reproduce:
1. Boot "boot.iso" parameters for booting: 'text console=ttyS0 utf8'
2. Do minimal install, I used text installation in console
3. Boot the installed system

Actual results:
[FAILED] Failed to start Create static device nodes in /dev.
See 'systemctl status systemd-tmpfiles-setup-dev.service' for details.

[FAILED] Failed to start Recreate Volatile Files and Directories.
See 'systemctl status systemd-tmpfiles-setup.service' for details.


Expected results:
Starting Create static device nodes in /dev...      [ OK ]
Starting Recreate Volatile Files and Directories... [ OK ]

(Not exactly, but you get the gist)
