But there are plenty of people who have bugged/begged me to add windows file streams because they were *convinced* it was a critical feature. And I dare say bug-for-bugs Windows compatibility was worth millions of $$$ of potential sales, which is why they agreed to add it --- and why I kept on getting nagged to add that feature to ext4 (and I pushed back where the Solaris developers caved, so there. :-) As for things like System V IPC support, that was only added to Linux because it was worth $$$, because enterprise databases like DB2 and Oracle demanded it. Is that evidence of "cancer"? You might not want it, but that's a great example of "one person's bloat is another person's critical feature". Or consider the dozen plus BSD sockets interface, which if removed would mean no TCP/IP support, and no graphical windowing systems. Critical feature, or bloat? But hey, if you only want V7 Unix, why are you complaining? Just go and use it, and give up on all of this cancerous new features. And I promise to get off of your lawn. :-) Cheers, - Ted
