Hi Michael, I really enjoyed your tutorial on Linux CLI. Your explanations are always clear and easy to follow. I was wondering if you could create a tutorial on Emacs? It’s such a powerful tool, but it can be quite daunting for beginners. I’m sure a playlist from you would help many of us get started with it. Thanks for considering this!
One should mention the performance penalty incurred by using COW snapshots. Many years ago when I discovered snapshots I decided that I would setup my Linux server to emulate another system i had worked with (I think maybe a netapp filer) and decided to setup automated hourly, daily, and weekly snaps. The performance was horrific and made the system totally unusable because of the write amplification which happens. Snapshots are a neat idea but I have never seen anyone use them for anything useful in production in my 30 years of professional Linux administration. A shame, really. I expect the situation is different with btrfs as opposed to LVM but I haven't played with btrfs or seen it used in production yet.
LVM is interesting, definitely a lot of powerful features... But it is combersome and somewhat confusing ... I would hardly implement it is production or for personal use since it can be very disconnected from the hardware in use and the commands are not so easily predictable or easy to remember

I agree, hopefully we will see soon new in-depth videos about btrfs
VERY very GOOD video
