I still have the manual activate LVM volumes work-around in place:

mondschein:/etc/initramfs-tools> cat ./scripts/local-top/lvm-manual
#!/bin/sh

PREREQ="lvm"
prereqs()
{
        echo $PREREQ
}

case $1 in
prereqs)
        prereqs
        exit 0;
esac

. /scripts/functions

log_begin_msg "Activitating logical volumes (as it does not seem to be done 
automatically at the moment)."

vgchange -ay

log_end_msg


So I am not sure. I am reluctant to deactivate it during Debconf. The network 
seems to be good enough for remote console access, but I´d still feel more 
comfortable when I am nearer to the office. I will ponder it and maybe still 
do it during the Debconf.

Thanks,
