I remember an operating system called ”Primos” by Pr1me. You could
specify exactly what could be done with a file or a directory and by
whom. I don't know exctly, but it could look something like this:
User1: darwx
User2: arw
$rest: ar

Maybe I remember it wrong, but something like that anyway. If you had
all permissions, it looked like:
User3: dalurwx

rwx was the usual read, write and execute. I think a was for ”access”,
d for ”delete” but I don't remember what l and u was.
Maybe l was for ”list” and u was for… like what? ”update”?
I also think that * meant ”all permissions”.

I think you can install something like this in Ubuntu:
sudo apt-get install acl

I found this page:

Maybe a possible solution?
