polkitd - 122-3 main

polkit is an application-level toolkit for defining and handling the policy
that allows unprivileged processes to speak to privileged processes.
It was previously named PolicyKit.
.
It is a framework for centralizing the decision making process with respect to
granting access to privileged operations for unprivileged (desktop)
applications.
.
In a typical use of polkit, an unprivileged application such as gnome-disks
sends requests via D-Bus or other inter-process communication mechanisms
to a privileged system service such as udisks, which asks polkitd for
permission to process those requests. This allows the application to carry
out privileged tasks without making use of setuid, which avoids several
common sources of security vulnerabilities.
.
This package provides the polkitd D-Bus service and supporting programs.
The pkexec program is not included, and can be found in the pkexec package.
