Allow user space file locations (rootless support) Why: Running dropbear as a user (rootless) is aided if files and programs can be saved/removed without needing sudo. What: Use the same convention as DROPBEAR_DEFAULT_CLI_AUTHKEY; if not starting with '/', then is relative to hedge's /home/hedge: *_PRIV_FILENAME DROPBEAR_PIDFILE SFTPSERVER_PATH default_options.h commentary added. Changes kept to a minimum, so log entry in svr_kex.c#163 is refactored. From: Generated hostkey is <path> ... <finger-print> to: Generated hostkey path is <path> Generated hostkey fingerprint is <fp> Otherwise the unexpanded path was reported.
