User Notes:

Installation of Umockdev

Install Umockdev by running the following commands:

./configure --prefix=/usr    \
            --disable-static \

To test the results, issue: PATH=$PATH:/sbin:/usr/sbin make check. The addition to PATH is needed if you use the starting scripts in The Bash Shell Startup Files, because some tests need to run udevadm.

Now, as the root user:

make install
