Linus just created a kernel that can be used with a Unix-like system. The difference here isn't academic, what I am talking about above was created before Linus was born. (mildly interestingly, he apparently missed Unix Epoch by only a few days)
After looking at Git I wonder how Linus could ever constraint himself to POSIX? How come linux system calls don't have ten optional parameters each? Some of them actually mandatory, some changing meaning of the whole call?
Why go with boring open, creat, read, write when you can have rerere and prune and annex and reflog?
Not sure what you're getting at here, git developers got to choose their own names for git commands because there was not an existing standard that they were trying to implement.
Do you really think that 'prune' is a worse name than, say, 'fcntl'?
