Well, doing this directly in such a critical place as /etc gives me
the willies, but it's your neck, I suppose. I can, anyway, help with
the "check it back out on top of itself" problem. Do this one time;
after that, svn will work directly on the files:

        svn co http://host/wherever/whatever/etc /tmp/etc # check out temp copy
        cd /tmp/etc
        find . | cpio -pdlmuv /etc

I'm assuming here that /etc and /tmp are on the same partition; in
that case, the "-l" makes cpio merely link the files, not copy them.
If your /tmp and /etc are not on the same partition (my, you *are*
adventurous, aren't you?), then put the one-time checkout somewhere
on the same ptn as /etc. It could be, say /etc/svn-etc-tmp.

And, of course, you'll need to do all this as root, since it *is* /etc and all.

You might want to pause between that "svn co" and that "find|cpio" to
compare the two directories vewy, VEEEEWY cawfully, checking that all
the expected files and directories exist, that their contents are
identical, and that their permissions are identical. If that ain't
so, don't proceed!
