Thanks, Eelco! I've just tried to fetch a fresh installation CD and
did a fresh install with the updated expression as you advised. The
result was the same - e.g. old sleuthkit 3.2.2 has been installed. I
also tried to fetch a development source tree via nixos-checkout and
build with 'nixos-rebuild -I' to no avail. Should I wait until your
changes propagate to the new version of the installation CD
image/repository or I can use your changes earlier somehow?
