The acl package contains utilities to administer Access Control Lists, which are used to define more fine-grained discretionary access rights for files and directories.
This package is known to build and work properly using an LFS-7.5 platform.

Install acl by running the following commands:
sed -i -e 's|/@pkg_name@|&-@pkg_version@|' \
include/builddefs.in &&
INSTALL_USER=root \
INSTALL_GROUP=root \
./configure --prefix=/usr --libexecdir=/usr/lib --disable-static &&
make
For meaningful results, the tests need to be carried out on a file system that supports extended attributes. It is also required that Coreutils is re-installed after acl is installed so that the extra acl bit displays correctly on a ls command.
Now, as the root user:
make install install-dev install-lib && chmod -v 755 /usr/lib/libacl.so && mv -v /usr/lib/libacl.so.* /lib && ln -sfv ../../lib/libacl.so.1 /usr/lib/libacl.so && install -v -m644 doc/*.txt /usr/share/doc/acl-2.2.52
You should now re-install Coreutils and proceed to run the test suite.
There are three sets of tests that come with this package. The
local partition where the tests are run must be mounted with acl
configured as described below. Additionally, the users bin and daemon
must be created or modified to have a proper shell and home
directory and the group daemon must
be a member of the bin group. The
kernel must also be configured with the appropriate ACL options
(there are nine different options).
To run the standard tests run make
tests . As root
user, run make
root-tests.
The third set of tests are Network File System (NFS) specific. See the contents of the test files in the test/nfs/ directory for the setup requirements.
sed -i ... include/builddefs.in: This command modifies the documentation directory so that it is a versioned directory.
--libexecdir=/usr/lib: This
switch ensures that libacl.la is
installed in the correct directory, and that a spurious
libacl.so symlink is not created in
/usr/libexec/.
--disable-static: This
switch prevents installation of static versions of the libraries.
There is no configuration to acl itself, but to get any use out of acl, a filesystem needs to support access control lists.
One way to achieve this is to add the acl option to an ext3
filesystem in the /etc/fstab file
as shown below:
# file system mount-point type options dump fsck # order /dev/sda1 / ext3 defaults,acl,user_xattr 0 2
