None of the files in /bin/ are executable on my Gentoo system. Should I file a Gentoo bug for that? - Grant

Should they be installed executable? I used update.sh recently and had to make it executable first.

That is a standard security measure in many packages such as this, don't have anything executable unless it is necessary. If you need to run those scripts, make them executable

why?

bash /path/script.sh works

but it does not work for standard exploits which mostly rely on script is executeable by a direct call and most exploit does not try to handle noexec-mounts and call the interpreter with the script as argument and in many cases it's simply impossible to call it this way because you don't have the full shell for your exploit - so they fail

Does the Roundcube process that checks your installation from a browser (can't remember the name) require one of these scripts to be made executable?
