Installing Debian GNU/Linux etch-and-a-half

Overview

The etch-and-a-half release is essentially just the most recent point release for etch, but with a more recent kernel (version 2.6.24). The main purpose of this release is to allow installation of etch on systems not supported by the 2.6.18 kernel that is used in regular etch installs.

For further details about scope, purpose and limitations of the etch-and-a-half release, see the Release Notes.

Installing

For new installations of etch-and-a-half the current release of Debian Installer for lenny is used, with minor changes for compatibility with etch.

Please read the notes below carefully before installing etch-and-a-half.

Because the current lenny installer is a beta release, it may have some errata you would not expect in a stable release. See the errata section at the bottom of this page for details.
The lenny installer includes a number of changes from the etch installer. See the release announcements for the beta1 and beta2 releases of the installer for an overview of changes.
This includes changes that affect preseeding (automated installations). See the appendix on preseeding in the Installation Guide for lenny (linked below) for correct preseeding options.

The following installation options are available to install Debian GNU/Linux etch-and-a-half.

netinst CD image (generally 135-175 MB)
- Only available for selected architectures.
- Will automatically install etch-and-a-half.
- Will automatically install the 2.6.24 kernel.
- Can optionally be used in combination with images from the current full CD/DVD set for etch. After the installation of the base system, the installer will ask if additional CDs should be scanned; at that point insert CD1 or DVD1, or the KDE or Xfce CDs.
Images: [amd64] [i386]
businesscard CD image (generally 20-50 MB)
- Available for all architectures.
- Needs to be booted with the option 'suite=etch' to install etch-and-a-half.
- Will automatically install the 2.6.24 kernel.
Images: [alpha] [amd64] [arm] [hppa] [i386] [ia64] [mips] [mipsel] [powerpc] [sparc]
netboot images
- Available for all architectures.
- Needs to be booted with the option 'suite=etch' to install etch-and-a-half.
- Will automatically install the 2.6.24 kernel.
- Other images than netboot (usb stick, floppy) may be usable, but have not been tested.
- Images for subarchitectures that will be supported in lenny but are not supported in etch, may not be usable.
Images: [alpha] [amd64] [arm] [hppa] [i386] [ia64] [mips] [mipsel] [powerpc] [sparc] [s390]

Additional notes

For the netinst and businesscard CD images, MD5SUMS and SHA1SUMS files are available from the same directory as the images.
There are two reasons the netinst image is only available for selected architectures. First, a lot of architectures don't really have new hardware that is not supported by the 2.6.18 kernel. Second, some architectures are most commonly installed using netboot, making the CD image unnecessary.
