But after discussing with my mentor, I've realised it's better to have regular updates. I will now keep posting blogs every alternate day, if not everyday. Achievements so far : In the last post I mentioned that I have created a page that lists all the Operating Systems that haven't yet reached their end of lifecycle, this was basically similar to the page that would come up when we press the show more button in Download an OS option. Now the challenge was to remove the Operating Systems that do not support tree based installations from this list. I initially tried keeping only the Operating Systems that were returning true for tree.hastreeinfo() but when I tried printing the kernel and initrd path for them, some returned null. While my mentor suggested an approach to re
