Introduction to Bubblewrap

Bubblewrap is a setuid implementation of user namespaces, or sandboxing, that provides access to a subset of kernel user namespace features. Bubblewrap allows user owned processes to run in an isolated environment with limited access to the underlying filesystem.

This package is known to build and work properly using an LFS-11.2 platform.

Installation of Bubblewrap

Install Bubblewrap by running the following commands:

mkdir build            &&
cd    build            &&
meson --prefix=/usr --buildtype=release .. &&

Next, if you desire to run the test suite, fix an issue caused by the merged-/usr configuration in LFS:

sed 's@symlink usr/lib64@ro-bind-try /lib64@' -i ../tests/libtest.sh

To test the results, issue: ninja test

Now, as the root user:

ninja install
