It does not execute any code from the package (as root or as anyone else) at install time. For example, Fedora recently allowed unprivileged users to install RPMs from their repository the packages executed as root as they installed. But Microsoft put it in so they could blame the users and shift responsibility for their completely broken trust model.įirst, let’s clarify what is meant by “without root permissions”, because there are two possible interpretations. Have you ever looked at the “details” of any of those UAC dialogs? They don’t say what the action is going to be, they usually have a CLASSID of some random control instead of a name, they provide no useful information for a decision. See Microsoft UAC for a classic example of this. But the reality is, you didn’t give them the tools to be smart about the security in the first place, so you shouldn’t have introduced the tool. That way, when the hapless user gets social-engineered into downloading and running the latest rootkit, you can just shrug and say “it’s the user’s fault, they accepted the certificate!”. This is Microsoft mentality – put in a new whiz-bang feature, but make the actual SECURITY of the feature insanely hard. The point is, you (or whoever) are creating an application to make it totally easy to download and run an app without root permissions, but then you’re saying the security is okay because you have to decide to trust someone, verify their identity (how?) and then accept keys and such to allow the one-click run to happen. Okay, yes, I see that you can trust “someone”, but there’s no real trust model. Sudo apt-get install zeroinstall-injector

The system can automatically check for updates when software is run. Each version of each program is stored in its own sub-directory within the Zero Install cache (nothing is installed to directories outside of the cache, such as /usr/bin) and no code from the package is run during install or uninstall. Zero Install is a decentralized installation system (there is no central repository all packages are identified by URLs), loosly-coupled (if different programs require different versions of a library then both versions are installed in parallel, without conflicts), and has an emphasis on security (all package descriptions are GPG-signed, and contain cryptographic hashes of the contents of each version). The user controls which version of the program and its dependencies to use. Any dependencies of the program are fetched in the same way. It takes the URL of a program and runs it (downloading it first if necessary).
The Zero Install Injector makes it easy for users to install software without needing root privileges.
