Not sure about the answer to your third question. In theory, once you've
set it, it should stay set - I don't know why it wouldn't still be set
after a reboot. But as to your first/second question, setting /tmp sticky
is really only important if you've got more than one user for your machine.
If you're the only one using it, it doesn't matter because you know if you
can trust yourself. :-) The sticky bit is important on a world-writable
directory when you've got multiple users for your machine, because with the
sticky bit set, only root and the user who created a file in that directory
can delete it. (Deletion is a function of directory permissions, not file
permissions.)
