Polkit-122
Installation of Polkit
There should be a dedicated user and group to take control
of the polkitd daemon after it is
started. Issue the following commands as the
root user:
groupadd -fg 27 polkitd &&
useradd -c "PolicyKit Daemon Owner" -d /etc/polkit-1 -u 27 \
-g polkitd -s /bin/false polkitd
Install Polkit by running the following
commands:
mkdir build &&
cd build &&
meson --prefix=/usr \
--buildtype=release \
-Dman=true \
-Dsession_tracking=libelogind \
-Dsystemdsystemunitdir=/tmp \
-Dtests=true \
-Djs_engine=duktape \
.. &&
ninja
To test the results, first ensure that the system
D-Bus daemon is running,
and both D-Bus Python-1.3.2 and
dbusmock-0.28.7 are installed.
Then run meson test -t3.
Now, as the root user:
ninja install &&
rm -v /tmp/*.service
Command Explanations
--buildtype=release: Specify a buildtype
suitable for stable releases of the package, as the default may
produce unoptimized binaries.
-Dtests=true: This switch allows to run the
test suite of this package. As Polkit is
used for authorizations, its integrity can affect system security.
So it's recommended to run the test suite building this package.
-Djs_engine=duktape: This switch allows using the
duktape-2.7.0 JavaScript engine. Replace with
-Djs_engine=mozjs for using the JS-102.8.0
JavaScript engine.
-Dauthfw=shadow: This switch enables the
package to use the Shadow rather than the
Linux PAM Authentication framework. Use it
if you have not installed Linux PAM.
-Dintrospection=false: Use this option if you are certain
that you do not need gobject-introspection files for polkit, or do not have
gobject-introspection installed.
-Dman=false: Use this option to disable generating and
installing manual pages. This is useful if libxslt is not installed.
-Dexamples=true: Use this option to build the example
programs.
-Dgtk_doc=true: Use this option to enable building and
installing the API documentation.
Configuring Polkit
PAM Configuration
![[Note]](../images/note.png)
Note
If you did not build Polkit with
Linux PAM support, you can skip this
section.
If you have built Polkit with
Linux PAM support, you need to modify
the default PAM configuration file which was installed by default to get
Polkit to work correctly with BLFS. Issue the
following commands as the root
user to create the configuration file for Linux PAM:
cat > /etc/pam.d/polkit-1 << "EOF"
# Begin /etc/pam.d/polkit-1
auth include system-auth
account include system-account
password include system-password
session include system-session
# End /etc/pam.d/polkit-1
EOF
