I have implemented LFS once, so I'll be happy to give you my impressions: 1) The LFS manual will get you to a base Linux system. Think of it as the minimal system required to get you up and running and nothing more. You will need to use BLFS or something else to get yourself to point where you will most likely be comfortable (especially as an Ubuntu user). 2) There is no package management by default. The manual recommends some ways to handle this including rebuilding the entire system from scratch (!) when you want to upgrade. So, after all of the work you do (which is mostly watching things compile) you are still responsible for maintaining all of your installed applications. For the average Linux system, this is a lot of packages. 3) All of that said, it is an interesting process to go through if you would like a little more insight into how a Linux system works, assuming that you take the time to understand what you are doing (and why) and not just blindly follow the manual. Shortly after completing the project (completed over a weekend), I found that I had learned a lot but had no desire to maintain the system. I believe (don't quote me on this) that the creator of Arch Linux started from LFS. In the end, I use Linux Mint. It's like Ubuntu with a better organized interface (IMHO) and more attention to visual detail. Should you try LFS? Sure, why not? It won't kill you and maybe it will spur some new project or idea in you. Worst case scenario, you spend a few hours rebuilding a machine. Hope this helps.
