Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

Is there a debian/ubuntu policy on softlinking things to another location in opt once they're installed properly in usr/share or usr/lib?

Here's a simple example: Packaging up dnsenum. It's a REALLY simple package (4 files).
A perl script, two wordlists, and a readme.

So from what I gather:
The wordlists should go in usr/share/dnsenum/*
The perl script itself would go in usr/lib/dnsenum/
The readme would go in usr/share/doc/dnsenum/

Add a wrapper bash script that goes in bin and just passes arguments to dnsenum.pl.

The question is this:

If there are various tools that provide wordlists or some other shared resource, is there a policy on linking all the wordlists from different packages in to /opt/wordlists/ ?

It seems like the "right" thing to do respecting the directory structure while still making things convenient.

Are you aware of any packages which install anything in /opt/? FHS does not seem to prohibit this (pathname.com/fhs/pub/…) but I never saw the package manager to install anything in /opt. I always thought this directory is for manually installed "add-on application software packages" –  Sergey Dec 3 '12 at 0:57
    
@Sergey Yeah, I know /opt is sort of a free-for-all and Ubuntu policy is third party software installed through software center goes there. That's why I asked (Ubu policy). –  hbdgaf Dec 3 '12 at 1:39

Ubuntu follows the FHS. Ubuntu packages install everything into /usr/. Runtime data can live in /var/lib/PACKAGENAME, and some critical early-boot things that live outside /usr, in /bin, /lib, etc.

So, your wordlists would go into /usr/share/dnsenum, yes. The script would probably just go into /usr/bin, and the documentation would go into /usr/share/doc/dnsenum.

Ubuntu doesn't put anything in /opt. However, third party applications distributed through the software centre have everything in /opt, to keep them separated from the rest of the system. These are not part of the distribution.

There's nothing special about data that's shared between packages, assuming it's still owned by a single package, depended on, by the others.

An example for word lists is /usr/share/dict/words, provided by dictionaries-common.
