Programs being uninstalled by being placed in the /proc

Do programs install themselves in the /proc directory by default or do you specify where they are to be installed. If a program/package is installed in the /proc folder, does this allow it to be uninstalled, or does it matter?

/opt packages are often pretty self-contained, having their own bin, lib, man directories and so on, and requiring updates to paths if the /etc/profile.d scripts aren't doing this automatically.

OpenOffice for example, Chrome sometimes (Depending from different distro packages), IBM tools for development or web deployment (many of them).
As you may notice "opt" stands for "optional" so something you may avoid on boot

/proc is a virtual file-system ie physically it does not exist. It represents 'the inside of' running kernel.

for example, (use 'ps' command to find out the process-id)
you need to find info related to process-id '2321'.
$ cd /proc/2321
$ ls -l
and you can find cwd, pwd, file descriptors and many more.

Any process that is running on linux machine, create a directory in /proc and have all the related info/links.
