Whenever I'm troubleshooting startup files, or shell scripts in
general, I find that running it like
[root at foo.com init.d]# sh -x httpd start
helps. It runs the script file and traces each line, so you can see
where it fails.
If it were a bad shebang line, I would expect to see (under CentOS 4.3)
[root at foo.com init.d]# ./httpd start
-bash: ./httpd: /bin/bashr: bad interpreter: No such file or directory
