Chapter 1. Package Updates
to install on an iSCSI target specified by in IPv6 address. The logic by which anaconda parses
IP addresses has now been corrected, but now requires IPv6 addresses to be specified in the
[address]:port form to comply with the relevant RFCs. This form removes ambiguity, since IPv6
addresses are still valid if they omit a sequence of bytes with zero values. When IPv6 addresses
are specified in this format, anaconda parses them correctly and installation continues as normal.

• comments in kickstart files are marked with a pound symbol (#) at the start of the line. However,
anaconda did not previously account for the possibility that users might mark a comment with
multiple pound symbols (for example, #####). Anaconda would therefore attempt to parse lines
that started with multiple pound symbols and installation would fail. Anaconda now recognizes lines
that start with multiple pound symbols as comments and does not attempt to parse them. Users can
now safely mark comments in kickstart files in this way.
• to avoid a circular dependency that exists between the ghostscript and ghostscript-fonts packages,
anaconda ignored ghostscript's dependency on ghostscript-fonts. However, ghostscript-fonts
was not explicitly installed as part of the Printing package group. The usefulness of Ghostscript
as installed by anaconda was therefore limited. Anaconda still avoids the circular dependency,
but now specifically installs ghostscript-fonts when users select the Printing package group.

• previously, anaconda did not automatically instruct the kernel to check for multipath devices when
installing on IBM System z systems. Therefore, unless users booted with the mpath boot option,
iSCSI devices detected on more than one path would be represented in the installer multiple
times, one for each path. Anaconda now automatically loads the mpath boot option and therefore
represents multipath devices correctly.
• Dell PowerEdge servers equipped with the SAS6i/R integrated RAID controller use BIOS Enhanced
Disk Drive Services (EDD) to identify the storage device from which to boot the operating system.
Previously, anaconda did not parse EDD to identify the correct boot device. Consequently, with a
RAID 0 and RAID 1 configured on the system, anaconda would choose the wrong device and the
system would not be bootable. Anaconda now parses EDD to support the SAS6i/R integrated RAID
controller, so that it selects the correct boot device for systems that use this device.
• previously, anaconda would always attempt to reconstruct pre-existing Logical Volume
Management (LVM) devices during installation. Anaconda would attempt to recreate the LVM
device even when a user cleared the LVM partitions from one or more of the disks that held
partitions that formed part of a volume group. In this case, installation would fail. Now, anaconda
no longer attempts to reconstruct incomplete LVM devices. Users can therefore safely re-
allocate storage that was once part of a volume group and installation will proceed as expected.

• when ksdevice=link is set in a kickstart file, anaconda should automatically select the first
available network interface and use it during installation. This avoids the need for user input and
allows installation to proceed unattended. However, if interfaces were in a state where anaconda
could not determine their status, anaconda would revert to interactive more and prompt the user
to select a network interface, thus making unattended installation impossible on systems where
network interfaces could be in such a state. Anaconda now forces the network interfaces on the
system into IFF_UP and IFF_RUNNING states before it attempts to obtain link status. Because
the interfaces are now in a state where they can report their link status to anaconda, Anaconda
can automatically choose one to use during installation and kickstart installations can proceed
unattended. (BZ#549751
