tl;dr:
set file ownership

hmmm, not much to say about this one, really. another "does what it says on the tin" type. i guess of interest is how it interacts with filesystem mount options as well as process capabilities
so, feel free to discuss those!

Why does chown need root? I've never understood this. It should be possible to chown one of your files to a different user or group yourself.

Programs assume that if you own a file or directory (and it is not world writable) then you also created its contents.

You still can't put it at a path where such software would trust it.
>>108388283
You don't have to do anything with it, and they can't put it in your home directory unless you made that other-writable (and you didn't, right?)
