I want to publish some software for different Linux distributions, using the regular Linux packaging formats (rpm, deb, yast, etc). My package will require a click-thru license agreement. Which Linux tools and package formats support a license in the package which is shown to the user before installing the software?
Linux support for click-thru licenses [closed]
.deb definitely does; the sun-java* packages from Debian non-free have one.
Keep in mind that on Linux (and other Unix systems), often an administrator installs the software, but different people actually use it. You may want to show your click-through license the first time each user runs the software.
(Well, actually, dpkg is text-based, so its not click-through, but rather type-through, but...)
As derobert said, on Unixy systems it's often not the end user who installs the software, so asking for the installer/admin to agree to the license may not be what you want (depends on the purpose of the software and the license text, I guess).
Click-through (or shrinkwrap which is slightly different but essentially the same principle) licenses have been a point of contention for years, as while there is an 'acceptance' by the user it's hard to prove that it was the user who accepted the license, and that the user actually read what was presented to them before using the software.
Take for example getting your lcoal mom+pop computer repair store to install/upgrade Windows; they usually click through the license pages so they can install all the other crap software they bundle onto the PC and the actual owner doesn't get a chance to read or agree to the license.
It's worth looking up the legality of that type of license in your jurisdiction and the jurisdiction of the users you intend to target.
I wouldn't rely on package management to do this for you either. I'd definitely have it as part of your application code. You could get a post install script for pretty much any package manager to run the click-through program if needed, but I think it's better to run it as a per-user thing.
If it matters, don't just look it up; ask a lawyer familiar with your situation (and your local laws, and licensed in your jurisdiction) if you need legal advice. –
Wellinformed
My question relates to the technology, not to whether I should be doing this or not. Your input is appreciated, but it's slightly off-topic to the question at hand. –
Tumbling
An RPM's installation script should not be used to prompt for questions because it there is no guarantee the code is running in a script. (it could be installed from the GUI and also people don't want the script to pause in a large installation transaction). You can name the license agreement the RPM uses and show it to users on either first run, or from their dowwnload site or by putting notes in the description.
