This is an imperfect example: dr--------. 1 chris chris 0 Oct 24 16:15 donotmove [chris@f20s ~]$ mv donotmove/ Videos/ mv: cannot move ‘donotmove/’ to ‘Videos/donotmove’: Permission denied' I own that directory. But because it's read only, I can't move it because moving it changes it. Of course if I become root, that overrides posix permissions, but the readonly status of a subvolume isn't like posix permissions and I see now reason why root should be able to modify it. And moving it does modify it.
