If you don't want to mess with compiling your own kernel you have a couple of options: 1) install an older RedHat kernel, reboot into that. 2) install a Mandrake kernel, reboot into that.

Sorry, it's not available for download atm. But I hear it wasn't that hard to customize the Knoppix CD. It's based on Debian, so the Debian package management tools should work for adding stuff to it and removeing unneeded things. Perhaps amanda client was even already included in the latest version of the original Knoppix distribution, not sure... There are some infos on customizing/remastering Knoppix CDs at http://www.knoppix.net/docs/index.php/KnoppixCustomizations Knoppix Lite ftp://ftp.es.debian.org/pub/miniKnoppix looks like a nice starting point for an amanda rescue CD.

One of my colleagues has built a bootable rescue CD based on the Knoppix Gnu/Linux distribution (see www.knoppix.net if you don't know Knoppix). His CD includes an amanda client besides our usual tools and goodies. I have just recently used this CD to clone two of our machines, testing the disaster recovery in case of a complate hard disk failure. Steps are: - booting from the rescue CD - setting up networking and starting sshd to be able to work comfortably from my workstation ;-) - partitioning the hard disk, setting up swap, creating file systems - mounting the root partition somewhere like /mnt/target - recovering the root partition using amrecover via the network - mounting the remaining partitions into the recovered root partition's mount points - recovering the remaining partitions - setting up tmp on the target partition (since /tmp is normally excluded from our backups), giving it the correct permissions - chrooting into /mnt/target and making the system bootable (quite easy with grub) - rebooting and testing the system. Works great if the new machine is identical to the old one. In my case, I ran into a (small) problem because the clone machines were only Pentium I while the original machine's kernel was built for Pentium II and higher. However, since Knoppix (and thus my colleagues's rescue CD) are based on Debian, "apt-get install"-ing an appropriate kernel wasn't very hard :-) The most tedious part of this procedure was changing the tapes (only a single DLT drive here). I should really take a look at the file: driver some time...

Re: Backup and recovery CD
For restoring linux based systems, I imagine that almost everything is already there on the KNOPPIX CD (http://www.knopper.net/knoppix/). You could boot from that (it would probably recognize some but not all hardware, test with your own), then you could compile and install amanda (with the correct configure options) and reconnect over the network to the backup copies of your indices. steven On Tue, 25 Feb 2003, Kevin M.

Backup and recovery CD
A number of commercial backup vendors ship bootable CDs with a copy of their backup application installed. You can use these CDs to restore a system that was totally toasted, due to massive disk failure, being hacked, etc. I'm wondering if anyone has ever developed something similar for AMANDA. I'm envisioning something like the Red Hat installer, which boots up, lets you drop into a limited shell and lets you partition disks. The AMANDA bootable CD would boot up, let you format disks and give you a limited shell, and then let you run amrestore by connecting to the tape drive (or whatever archival media you are using) of your remote backup server.
