Re-Imagining Linux Platforms to Meet the Needs of Cloud Service Providers

[ Thanks to Petros Koutoupis for this link. ]

""Apparently there had been some problems with the patch being merged into the Linux kernel for a number of reasons. (1) Montavista was attempting to patent some of the concepts and algorithms used in the file system (in 2004) and (2) even after the dropped the idea of patenting their code, there was some discussion on the redundancy of having yet another file system implemented into the Linux kernel (in 2009). What that means, is that the Linux kernel already has two commonly used RAM file systems and a large number of other file systems. So why was there a need to write another one? Why couldn't Montavista patch already existing code? (3) It is also not a full featured file system in that it does not support symbolic links.

"I agree with this logic. Please do not misunderstand me. Montavista is a very respectable company that has done an excellent job in supporting embedded Linux. I am also glad to see them contribute to the kernel and in turn the community. But truth be told, tmpfs was build on top of the ramfs code. Why couldn't pramfs follow the same course of development. The GPL makes it easy to not have to re-invent the wheel."
