RHBA-2012:0967 - Bug Fix Advisory

Topic

Updated augeas packages that fix three bugs and add two enhancements are now
available for Red Hat Enterprise Linux 6.

Description

Augeas is a configuration editing tool. Augeas parses configuration files in
their native formats and transforms them into a tree. Configuration changes are
made by manipulating this tree and saving it back into native configuration
files.

This update fixes the following bugs:

• Previously, the "--autosave" option did not work correctly when using Augeas

in batch mode, which caused that configuration changes were not saved. As a
consequence, configuration changes could be saved only in interactive mode. This
update ensures that the "--autosave" option functions in batch mode as expected.
(BZ#759311)

• Prior to this update, when parsing GRUB configuration files, Augeas did not

parse the "--encrypted" option of the "password" command correctly. Instead, it
parsed the "--encrypted" part as the password, and the password hash as a second
"menu.lst" filename. This update ensures that the "--encrypted" option of the
password command is parsed correctly when parsing GRUB configuration files.
(BZ#781690)

• Previously, Augeas was not able to parse the /etc/fstab file containing mount

options with an equals sign but no value. This update fixes the fstab lens so
that it can handle such mount options. As a result, Augeas can now parse an
/etc/fstab file containing mount options with an equals sign but no value
correctly. (BZ#820864)

In addition, this update adds the following enhancements:

• Previously, the finite-automata-DOT graph tool (fadot) did not support the -h

option. Consequently, when fadot was launched with the -h option the "Unknown
option" message was displayed. This update adds support for the -h option and
ensures that a help message is displayed when fadot is launched with the option.
(BZ#628507)

• Previously, Augeas did not have a lens to parse the /etc/mdadm.conf file.

Consequently, the tool for conversion of physical servers to virtual guests,
Virt-P2V, could not convert physical hosts on MD devices. This update adds a new
lens to parse the /etc/mdadm.conf file, enabling Virt-P2V to convert physical
hosts on MD devices as expected. (BZ#808662)

All users of Augeas are advised to upgrade to these updated packages, which fix
these bugs and add these enhancements.
