Good point, I would really appredicate possibility to log-in even with
/ being read-only. It's true that making kernel work with
files... Well, ok! So make that syscall pass 'path to dev' or 'path
where to operete'. Do it on every such syscall. Then, kernel setting
permissions was more-or-less explicitly requested. Well, you did not
pass _full_ pathname, but I do not think that that matters too
much. What do you think?
