Build Your Own Linux Distro

Did it once with LFS (http://www.linuxfromscratch.org/). It is fun to do. One learns quite a bit about Linux. IMHO if one wants to work a Linux system administrator it is almost a must. However, it is absolutely no fun to keep such a system up-to-date. Changing dependencies. Following security advisories. It is a full time job. As software developer I prefer a standard distribution. Which one? Don't care. As a compromise I manage my most used tools... gcc/clang/qt/cmake... myself. This way no update can unexpectedly pull the rug from under my feet. I can easily change the distribution. And I learn about possible problems in my tools, which otherwise might be hidden due to distribution specific patches.
