I have just noticed that when doing a copy of a directory, the copy

This was my test directory. Here is my output during the initial
stage, just
after copying has begun:
drwxr-xr-x 4 root admin 136 Oct 29 22:56 Mixdown Project
And when the copy was complete:
drwxrwxrwx 8 jeffrey jeffrey 272 May 6 2005 Mixdown Project
I was sudo'd to do the cp.
Can someone tell me why cp is doing this?
There are several reasons.
Firstly, the mkdir(2) system call does not provide a way for the
owner/group to be set on the destination (since that would only be
useful to root, anyway).
Secondly, the directory has to be left as it was created until the
copy is complete because the final mode for the directory may
preclude creating files within it.
Those two cover most cases.
