I actually currently use
-----SNIP - EDITED FOR SECURITY -------------
syslog (LOG_NOTICE,"Changing directory/root to %s",path
if (chdir (path) || chroot (path)) return 1;
}else{
syslog (LOG_NOTICE,"No ("EDITED FOR SECURITY" ) directory
for %s: using main"
}
}
execv (argv[0],argv+1);
return 1;
}
-------END - SNIP --------------------------
