From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

The "starting over" part is what made it take so long for linux to "stick" with me.
Once it became "restore from an earlier image", it was a game changer!
Every time I install or configure anything, it's done via CLI and added to a script. Makes setup a breeze.
My game changer was circa 2014 when I broke something and got dropped to a basic shell and for the first time instead of panicking and immediately reinstalling I thought for a moment about what I had just done to break it, and undid the change manually. Wouldn't you know it booted right up like normal.
The lesson here: if it broke, you probably broke it, and if you know how you broke it, you know how to fix it.

"Starting over" is how we learnt Windows in the 90's too
Giving our computer ghonorrea by downloading Napster mp3s
I'd just re-install Windows over the top of the fucked up install normally. It was a bit easier to recover from, and a bit harder to fuck up
I could be weird for this but the starting over part actually contributed to me continuing to use linux tbh. Trying out a new distro, figuring out how to use it, and building a new user interface each time I killed my system kept me engaged with linux beyond its utility. It functioned essentially as a way to learn about computers and as a creative outlet. I don't fuck around and find out as much as I used to but I still swap distro every year or so.
It was similar for me, but not quite the same. The thing I hated was starting from scratch. I'm very much not a distro hopper. Back in the day, I enjoyed the challenge of trying to troubleshoot issues and get the system working again, and that kept me interested, but eventually, I'd hit a problem I couldn't resolve, and I'd have to start again from scratch, and at that point, I'd just go back to Windows.
Now, I still get to do the same thing. If I break it, I get to learn how I broke it and try and fix it, and I find that process compelling. But because I'm using btrfs restore points now, I don't get to the point where I have to start again from scratch. So I can work at solving it to the limit of my abilities, with confidence that if I can't work it out, it's not a huge issue.

Timeshift was a gamechanger
Timeshift itself borked my shit up. I had to reinstall all registered packages to fix its fuckups..
sudo aptitude reinstall '~i'Edit: Sure it took a long while, about as long as a full OS reinstall, but never once was there any issue with the kernel.
While only once, timeshift destroyed my bootloader. Don't update and reboot before a meeting, kids
My test of Timeshift was pretty simple and straightforward.
Fresh install Linux Mint
Install most of the main software I wanted.
Do a Timeshift backup.
Install some extra software I didn't necessarily need, but might want to use someday.
Restore the backup from step 3.
Results: Everything from step 4 was still registered as installed, but almost nothing from step 4 actually worked.
So I brute force reinstalled everything in place, and haven't used Timeshift since. I'm perfectly comfortable using the terminal, and at worst a live boot media, to fix any issues that might come up.
Timeshift is a good piece of software doing a tired trick.
The new hotness is copy on write file systems and snapshots. I can snapshot, instantly, then do a system update and revert to the previous snapshot also instantly.
Instead of using symlinks files, like Timeshift, the filesystem is keeping track of things at the block level.
If you update a block it writes a new copy of the block (copy on write). The old copy is still there and will be overwritten unless it is part of a snapshot. Since the block is already written, snapshots don't require any data to be copied so they're instant.
Once you finish the system update, all of the overwritten blocks are still there (part of the snapshot) and reverting is also just a filesystem operation, theres no mass data to be copied and so it is also instant.
It does use disk space, as allocated blocks AND snapshotted blocks are stored. It uses less than Timeshift though, since Timeshift copies the entire file when it changes
ZFS and btrfs are the ones to use.
Didn’t quite follow what you were saying completely. Are you suggesting a new program over time shift or change the file system type like ZFS and Btrfs? I’m using Ubuntu and not sure if I seen those before.
Snapshots are one of the features of copy on write filesystems like ZFS or btrfs.
It looks like Ubuntu has btrfs support, so you could do things like configure the package manager to automatically snapshot before a system upgrade.

That looks like a current guide for setting it up
Thank you for sharing!
I also can't get over the fact that it doesn't understand RAID or filesystems somehow.
