I am a little worried that there might be versions of "sed" that don't support
character classes. But maybe I am too old fashioned. This might in fact be
perfectly fine.

Also, we are probably OK with matching the comma before the "bind", but if you
want to be extra careful, match either a comma or white-space. Probably, do the
same at the end of the string, too.

 echo "$HOME/chroot/.${target} $HOME/chroot none rw,bind 0 0" |
   sudo sh -c 'cat >>/etc/schroot/mount-'"${target}"
 mkdir -p "$HOME/chroot/.${target}"
