This was my quick and dirty way to keep track of where I was when I installed LFS for the first time few weeks ago. Of course downloading does not mean installed but I disciplined myself to update the wget_log.txt if I don't install the package. I could certaily improve this two liner script with a time stamp of some sort. Maybe when I want to reinstall again. :) Anyway I very much enjoy LFS so far.
