This question already has an answer here:

I read some posts and parts of FHS to understand which directory I should install packages in. As far as I could understand /opt is for independent packages and /usr/local is for packages that are not maintained by distro repo's.

I want to install a network emulator called "mininet" on my Debian wheezy, so that all users can use it. It has an install.sh script which installs both types of packages: maintained by repo & not maintained by repo. As the first step of the installation I can indicate where I want my base directory to be. Now my question is which directory I should indicate as the base directory? should it be: "/usr/local", "/usr/local/mininet", "/usr/local/bin", "/usr/local/bin/mininet", "/opt" or some other directory?

I would appreciate if you could explain your answer too Thank you.

EDIT: Should I specify the name of the package in the path like we do when installing in /opt (e.g. /usr/local/mininet/) or I shouldn't?

If the base directory you mean is used for the --prefix option of ./configure or make, it should be /usr/local.

This way, the software can be installed into the subdirectories of /usr/local, like
/usr/local/bin, /usr/local/lib/mininet and /usr/local/man.

I did that once and I realized that the installer has created some files and directories outside of /usr/local/bin in /usr/local/.... is that compliant with FHS? –  Ahmet Aug 17 at 22:13
    
The FHS explicitly does not specify anything under /usr/local - so it's compliant. To me, it makes sense to use a structure like under /usr. –  Volker Siegel Aug 18 at 9:41

for mininet, probably the best way to install it is trying to use the ubuntu packages (option three at http://mininet.org/download/). This will put the package in /usr but more than that will allow you to uninstall the package, even in the case you are doing an upgrade, using apt-get, without leaving litter around your system.

Otherwise I suggest you to install it in /opt/mininet or something. Avoid /usr/local if possible, because all package will mix together and you won't be able to sort which file is related to which package should you want to remove something.

If you want the binaries or man pages to be usable by everyone you can manually put symlinks into /usr/local/... pointing to /opt/mininet/.... This would still let you distinguish which files are related to mininet and which ones aren't. –  pqnet Aug 17 at 18:21
