nofail mount option

Good to know. Thanks!

Thanks! Using -e jumped right to the problem:

Something—I don’t know what—added a removable drive to fstab, and the error was that drive couldn’t be mounted at boot.

I have two guesses:

1. I formatted a microSD card using YaST Paritioner sometime before doing the distro upgrade.
2. The drive might have been attached during the distro upgrade, though I don’t think it was.

At any rate, I commented out that line in fstab and it booted right up. Now I just have to fix snapper.

EDIT: Why is my -e red?
Testing
-f
-aBx

Weird. What I see when viewing mycomment on thelemmy.club:

No, I don’t think so. Turns out, I don’t need the rollback, so now I just need to fix snapper. (I updated my post)

Why not just write to USB directly?

cp debian.iso /dev/sdX

Because one single character typo and you just wiped out your system drive or some secondary HDD. It’s much safer to use a tool like Etcher.

This video I just watched the other day says otherwise (with clear evidence.)
