It is an unnecessary hack, since the intepreters all have standard locations. It also adds the overhead of a second exec() call and a PATH search (start env, let it parse its command line, then search the PATH for the desired interpreter, then exec() the interpreter). It also makes system scripts more fragile; for example, if somebody installs (from source) a different version of python in /usr/local/bin, all RPM-installed scripts in /usr/bin (that may not even work with that version) will now use the new version with unpredictable results. -- Chris Adams <cmadams@xxxxxxxxxx> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble. -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
