Commiting two working copies at once

Hi,
I keep my server config in subversion, I have some changes in /etc and
/var/apache that I'd like to commit because they are essentially the one
change.
However, when I run
  svn ci /var/apache and /etc
it simply says
  Aborted.

I'm guessing this is because / and /var are not working copies, so svn
assumes I am trying to check in two unrelated working copies (possibly
to different repositories).

Is there anyway I can commit these changes together?
