Bug 2182948

+++ This bug was initially created as a clone of Bug #2182947 +++

Description of problem:
When linking the '/etc/udev/rules.d/70-persistent-net.rules' file to /dev/null to disable this udev rule,  cloud-init still tries to write this file and modify the permission, which causes the permission changes of /dev/null from 666 to 644. In this case, the non-root users will have no write permission to /dev/null. 


This issue has been resolved upstream.  The commit summary is as below:

Version-Release number of selected components (if applicable):
cloud-init-22.1-8.el8.noarch


How reproducible:
100%


Steps to Reproduce:
1. Create an instance with RHEL-8.8 guest image on PSI OpenStack env
2. Create the symbolic link file as follows
# ln -sf /dev/null /etc/udev/rules.d/70-persistent-net.rules
# ll /etc/udev/rules.d/
total 0
lrwxrwxrwx. 1 root root 9 Mar 29 05:32 70-persistent-net.rules -> /dev/null
3. Rerun cloud-init
# cloud-init clean
# reboot
4. Login to the instance and check the mode of /dev/null
# ll /dev/null
crw-r--r--. 1 root root 1, 3 Mar 29 05:33 /dev/null
The mode bits have been changed from 666 to 644. And the non-root users will hit "/dev/null: Permission denied" error.
5. Check the cloud-init log
# cat /var/log/cloud-init.log
...
util.py[DEBUG]: Writing to /etc/udev/rules.d/70-persistent-net.rules - wb: [644] 96 bytes
