To obtain this, rebuild grep with the LFS Chapter 8 instructions after installing . To test the results, first disable one test that fails and prevents the other ones to run: mv tests/fsck-tests/012-leaf-corruption/test.sh{,.broken} To test the results, run (as the root user): make -j1 -k test If the above mentioned kernel options are not enabled, some tests fail, and prevent all the remaining tests to run, because the test disk image is not cleanly unmounted. Two tests fail for unknown reasons in the test-libbtrfsutil section. Tests take a very long time, and it may be interesting to run only part of them. Running tests only in one directory can be done with make TEST=<DIR> test. Install the package as the root user: make install && ln -sfv ../../lib/$(readlink /lib/libbtrfs.so) /usr/lib/libbtrfs.so && ln -sfv ../../lib/$(readlink /lib/libbtrfsutil.so) /usr/lib/libbtrfsutil.so && rm -fv /lib/libbtrfs.{a,so} /lib/libbtrfsutil.{a,so} && mv -v /bin/{mkfs,fsck}.btrfs /sbin --disable-documentation: This option is needed if the recommended dependencies are not installed. ln -s ... /usr/lib/libbtrfs.so: Creates a symbolic link in the directory where it is expected. rm /lib/libbtrfs.{a,so}: Removes unneeded library entries.
