I was given advice in #debian-boot to use in-target for this purpose, so I've
solved it like this:
d-i preseed/late_command string wget -q -O -
http://ahava/d-i/etch/late_command.sh > /target/root/late_command.sh && chmod
u+x /target/root/late_command.sh && in-target '/root/late_command.sh'
>> /var/log/syslog
Thanks to the kind developer at #debian-boot today!
