Description Christophe Besson 2020-09-12 08:27:30 UTC

Description of problem:
Booting on the DVD rescue mode fails with a tmpfs entry in /etc/fstab.
Need to backport the upstream patch.

Version-Release number of selected component (if applicable):
python3-blivet-3.1.0-21.el8_2

How reproducible:
100%

Steps to Reproduce:
1. Install a fresh OS
2. Add the entry below in /etc/fstab:
~~~
tmpfs  /tmp tmpfs rw,size=256m 0 0
~~~
3. Reboot on the DVD rescue mode

Actual results:
Got a python traceback and then "Pane is dead":
~~~
AttributeError" 'TmpFS' object has no attribute '_chrooted_mountpoint'
~~~

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.
