While I definitely see the value in sharing CLI knowledge and skills, I think
it's important to start with a link to a disclaimer along the lines of:
"On a desktop GNU-Linux system like Trisquel, installing software using
anything other than the package manager (via apt-get or a GUI like Synaptic
or Add/ Remove Applications), and especially compiling programs from source
code, can result in a number of things you may not expect, including but not
limited to:
* programs that don't run correctly, or at all
* problems identifying and installing dependencies; all the other programs
that the program you are trying to install needs to run correctly
* having to manually update to newer versions if and when they become
available (apt-get update will not help you here)
* having to manually uninstall the program if you no longer want it (apt-get
remove and apt-get purge will not help you here)
* security vulnerabilities, and /or race condition bugs, introduced into your
system due to a lack of testing of programs you've manually installed with
the distro you're using
When installing software that is not included in the default repositories of
the distro you're using, it's best to test the program on a clone system on a
separate partition, or another computer, running the same version of the same
distro. This makes it less likely that you will bork your main system, and
more likely that you will be able to connect to the net to seek advice on how
to fix any problems you run into.
Finally, when using a 100% free code distro like Trisquel (or Parabola or any
of the others endorsed by the FSF), installing software from PPAs, or from
the web, or compiling from source, can result in proprietary software being
introduced into your system."
Is there a page on the wiki communicating something along these lines? If
not, I will create one, and anyone is welcome to improve the text.
