Clarifications:
I produce “educational-style” videos to help me practice public speaking and tricky concepts. If these videos are helpful to you, that is fantastic, but please be aware of the original intent.
My videos will NOT give you an unfair advantage on any exam. The information in my videos is sourced from publicly available documentation and my own experience OUTSIDE of any exams I have taken. That information is also provided "as is" and is not guaranteed to be free from error.

Your viewership is greatly appreciated. Thank you!

Yo, just want to be another person to say that I passed RHCSA thanks to your videos! They have been extremely helpful, insightful, and intuitive. Also really liked your approach where you would show us the relevant part of the man-pages while teaching, so that we can review it again during exam, rather than relying on rote memorization. Once again, thank you, and cheers!

Thank you for showing this faster method and explaining the commands.

Took exam April 1st 2024, failed because of this. I can confirm this is the new method and rd.break does not work form exam.

RHCSA coming up in a few days for me - these videos have been an absolute gem. Thank You!

I just want say thank you for this video, Today I passed the exam and this video was very helpful to me.

i usually use the rd.break like the book, and it took time to boot, this one is a lot faster and well explained !

Thank you for your generosity in sharing your valuable knowledge.

Just passed RHCSA. Loved watching your series as part of my preparations! Wish you all the best and I will keep an eye on the future videos for sure :)

Your videos have been VERY helpful. They are really well done. Thank you!
I am using AlmaLinux 9.3. I followed the steps but had SELinux permission issues after booting into the normal system. I could not really do anything as root without permission denied errors. I rebooted again with 'init=/bin/bash'. Then I did 'touch /.autorelabel' and it fixed the issue. It did not take my system very long to relabel, but it is a fairly bare-bones system with no GUI, etc.

I retook my RHCSA 9 and passed after watching this video on how to reset the root password.
Thanks!!!🎉

Hi....The rd.break issue still seems to be there and i could not complete the questions on node2. I raised a ticket on this issue cis i think its not fare to loose the chance to pass the examm in the first attempt itself. Thank you so much for uploading the video and your explanation is awesome. Let me know if you are providing training on RH.

Hey! Thank you for this. The video was crystal clear to me and I loved the process.
Now, I got a question.
I have been practicing the root password reset with the rd.break and then the remount, rw for the /sysroot and post setting the password for root, making the .autorelabel file.
Do you recommend I do the above process for init=/bin/bash or stick to rd.break > touch /.autorelabel ?
My exam is scheduled for RHCSA v9 ; Awaiting your reply. Once again awesome stuff as always :)

Hey man, thx for the helpful content ♥
Do you happen to know if the current RHCSA exam is running on RHEL 9.0 or 9.3?
I'm asking because I've managed to recover root password on RHEL 9.3 both with good old rd.break, and with the method you showed in this video.

[zwuqrjm]

Your vid is so informative and thanks a lot for that!
I want to ask you 2 questions if you don't mind.

1. I tried init=/bin/sh insted of init=/bin/bash, and it simply didn't work. Many features weren't loaded, pid was not 1, etc. Is that because /bin/sh loaded too early?
2. After followed your instructions entirely, it worked like a charm. But while `su root` was working `sudo su -` didn't work. Is this sudo related problem?

I really like your way of teaching. Please keep going!

change context compared to restorecon is not a recipe for persistence after you boot up. Which is transient or only work during durring runtime.

[danielngo]

Your videos are the best, does your playlist cover every single objective on the exam?

[janke]

2:58 What does 'restart signal' mean, is it performed by CTRL + C?

[balloth]

IMHO, the "systemd.debug_shell" kernel parameter is better, you end up with a root debug shell on tty9 and SELinux is still on, so you don't have to change the /etc/shadow context after changing the root password.
