As yet, the Ubuntu installer only supports a subset of Kickstart’s features. The following is a brief summary of features that are known to be missing:
• LDAP, Kerberos 5, Hesiod, and Samba authentication.
• The auth --enablecache command to enable nscd.
• Upgrades. To upgrade from one Ubuntu release to another, use the facilities provided by apt and its frontends.
• Partitioning of multiple drives. Due to current limitations in the partition manager, it is only possible to partition a single drive.
• Using the device command to install extra kernel modules.
• Driver disks.
• Firewall configuration.
• Installation from an archive on a local hard disk or from an NFS archive.
• The logvol --percent, --bytes-per-inode, and --fsoptions options for certain kinds of detailed Logical Volume Management (LVM) configuration. (LVM configuration in general is experimentally supported as of Ubuntu 9.04; please let us know about your experiences with it.)
• Restrictions of a partition to a particular disk or device, and specifications of the starting or ending cylinder for a partition.
• Checking a partition for bad sectors.
• RAID configuration.
• Exclusions in %packages sections are no longer supported as of Ubuntu 6.10, as a casualty of other improvements. You may need to use a %post script instead to remove unnecessary packages.
• Pre-installation scripts and non-chrooted post-installation scripts may only be shell scripts; other interpreters are not available at this point in the installation.
