Description of problem:
I encountered this exception after the execution of liveinst.

Version-Release number of selected component (if applicable):
anaconda-23.17-1

How reproducible:
I haven't tried to reproduce it.

Steps to Reproduce:
1. Boot Fedora-Live-KDE-x86_64-23_Alpha-TC2.iso
2. Launch 'liveinst' via konsole
3. Install the system, following this TestCase: https://fedoraproject.org/wiki/QA:Testcase_partitioning_guided_multi_empty_all
4. Set a password for root, do not create a standard user.
5. Close 'liveinst'.

Actual results:
1. Anaconda seems to run fine and the new system is installed properly.
2. This traceback is printed on the terminal emulator:

Error in atexit._run_exitfuncs:
Traceback (most recent call last):
    File "/sbin/anaconda", line 91, in exitHandler
        os.unlink(pidfile_path)
        FileNotFoundError: [Errno 2] No such file or directory: '/var/run/anaconda.pid'


Expected results:
1. I don't know what consequences causes this (if any), but ideally liveinst should not crash on exit.


Additional info:
I was testing on a qemu-kvm guest, with two empty virtual disks (both 10gb).
