Something that didn't make sense -- case sensitivity
At some point while transferring files from my old System76 laptop to my new System76 laptop, something weird happened, and it made no sense to me at all.
I was using Dolphin, split-pane, and had old_laptop on the left and new_laptop on the right. Both laptops' hard drives are formatted as ext4. While copying a directory, Dolphin's prompt came up asking if I wanted to rename/overwrite/skip file_something_or_other, meaning it thought file_something_or_other already existed. But it didn't. Couldn't, as this was an empty partition.
A closer look showed that file_something_or_other was actually file_something_or_Other and a different file, file_something_or_other, had already been copied. It thought they were the same name--like on window$.
IOW, it was disregarding case-sensitivity, and seeing them as the same name. WTF?! 
In 35 years of using *nix I've never seen this happen, nor would I expect to. There is no question that the files being copied were on an ext4 hard drive going to an ext4 hard drive. Any ideas on how/why this happened?
To get around it, I temporarily renamed file_something_or_other to file_something_or_other_2 and then changed it later at a command line. I cannot reproduce it now, using the same source and destination directories. I've reinstalled 20.04 about a thousand times since it happened...so maybe something was screwed up somehow...?
