(debian theme is less stupid now, so i set it to the highest priority in
the pkg-ltsp main branch)

i would suggest removing the debian-edu theme from ldm, adding it to
debian-edu-artwork, and setting the priority for the debian-edu ldm
theme to a very high number in the debian-edu-artwork postinst (on the
presumtion that debian-edu-artwork implies that you want debian-edu
themes over other themes). that way, a non debian-edu install will still
default to the "Debian" theme (and on ubuntu, presumably "Ubuntu" will
be default).

so, in the debian-edu-artwork postinst:

update-alternatives \
    --install /usr/share/ldm/themes/default \
    ldm-theme /usr/share/ldm/themes/Debian-Edu 80

at the moment, debian-edu could enable the appropriate theme with
something in the debian-edu-ltsp script (if that's still being used)
like:

chroot /opt/ltsp/ARCH update-alternatives --set ldm-theme /usr/share/ldm/themes/Debian-edu


debconf code could use update-alternatives to get a list of available
alternatives, and then prompt for it (probably at low or medium
priority). i think the alternatives system still makes sense for this
sort of thing, providing a default, while making it possible to easily
override the default.

could we use lsb_release in the postinst to set the defaults differently
on ubuntu or debian systems?

live well,
