Need to backport the upstream patch.

1. Install a fresh OS
2. Add the entry below in /etc/fstab:

Got a python traceback and then "Pane is dead":

python3-blivet-3.2.2-3.el8 is available in RHEL-8.3 Beta, which fixes this problem.

Reproduced using RHEL-8.2 GA.
Verified on a RHEL-8.3 compose with python3-blivet-3.2.2-6.el8.

Moving to VERIFIED.
