In the book "Systems Performance" by Brendan Gregg, there is a section on Kernels--in this case comparing Linux to Solaris--where the author shows a table of Kernel Versions with Documented Syscall Counts. He states: '...there is a pattern over time: Linux has been adding system calls. Solaris has been removing them...' Just as a matter of personal opinion, I would personally never jump into Linux Kernel Development simply because I feel there are already 'too many cooks in the kitchen' and it feels as if there is simply not as much clarity when compared to other *nix distributions. Do I work with Linux? Yes, because this is what is used in my workplace. Would I hack on the Linux Kernel or Network Stack for work purposes? Sure, because it would likely be a group effort to address some problem for instance. Now would I go home and hack on the Linux Kernel for fun and understanding? Absolutely not.
