I stumbled upon this issue when I ran lh_binary first.  It was installing
many java packages (gcj, bsh, openoffice.org-java), which I didn't request.
I recognized that these were the same packages that aptitude was trying to
install before I had turned recommends off (openoffice.org was recommending
it, I believe).
     I then looked at the command tree at the wiki, and ran all the commands
in order, until I ran 'lh_chroot_sources install' and it tried to install
the packages again.  I then googled that script and I found some stuff about
putting 'apt-get dist-upgrade' in the script at some point.
     In chroot, I tried apt-get dist-upgrade, and sure enough, it tried to
install the packages.  However, when I gave it the option
--no-install-recommends, it didn't try to install them.
     I then returned to the script, and opened it in an editor.  I found the
only place in it where it called 'Apt dist-upgrade'.  I looked in
/usr/share/live-helper/functions/ and found 'Apt' in wrapper.sh,  and
verified that it was calling
    case "${LH_APT}" in
        apt|apt-get)
            Chroot apt-get ${APT_OPTIONS} ${@}
            ;;
and that
LH_APT="apt"

I then put in the line
echo ${APT_OPTIONS}
in lh_chroot_sources right before the 'Apt dist-upgrade'
when I ran it again, it printed out '--yes' and nothing else.

I tried setting the apt settings in chroot to disable recommends.
Apt-config said *APT*::Install-*Recommends* was equal to '1'  when I set it
to '0', it didn't work, but when I set it to 'false' it stopped the
unnecessary packaging at least in chroot.

However, lh_chroot_sources was still trying to install them, so I gave up
and added --no-install-recommends to the Apt dist-upgrade line and it
worked.

I am using both chroot_local-packages and chroot_local-packageslists and a
custom repository for both binary and chroot, if that means anything.  I
don't believe I was missing any script because I first got this problem when
running lh_chroot, then lh_binary.  However, I was doing many retries
(mostly lh_build) on it previously, with only a lh_clean --purge in between.

I hope this helps you
