Hi,
I have a question on the open ssh code (any version). when a request to run a subsystem (say sftp) is received by SSHD, why fork and exec a shell with '-c .../sftp-server' instead of directly fork-ing and exec-ing sftp-server? What value does the shell add? I know this is a common approach and may have nothing to do with SSH/SFTP in general but I wanted to understand the reasoning behind this. TIA
