The pirate scene occasionally hits this as well (copies of the film "Con Air" which would be named "Con.Air.<foo>" by convention were instead named "Con_.Air" or "Con_Air" etc. All thanks to the legacy CON device.

Same thing in Cargo: http://sasheldon.com/blog/2017/05/07/how-i-broke-cargo-for-w... https://github.com/rust-lang/cargo/issues/3982

... and the Linux kernel itself.

I learned about this when I added cloning the Linux kernel repository to an integration test suite for a cross-platform filesystem. I had to use another project because of that file :)

I ran into it while trying to clone the source for Minix, just to poke around and read the code. (I think it was COM and not AUX but same principle)

Me as well while cloning linux on windows

You run into different, but similar, issues cloning Linux on macOS as well, since HFS+ is case-insensitive by default (and looks like the same is true of APFS), but the Linux source has filenames that differ only in case (don't ask me why).
