If you look at Giorgio's last updates at GitHub Koreader there is a new koreader_kobo.sh.

# we're always starting from our working directory
cd /mnt/onboard/.kobo/koreader/

# export trained OCR data directory
export TESSDATA_PREFIX="data"

# export dict directory
export STARDICT_DATA_DIR="data/dict"

# stop nickel
killall nickel

# finally call reader
./reader.lua "$1" 2> crash.log

# continue with nickel
reboot

My guess is that this is what he intended to go with the other changes he made.
