Occasionally, in the past, I have upgraded a debian system, after which it no longer boots successfully. Unfortunately, for these complex systems, neither the install/boot media, nor knoppix, result in access to the files necessary to recover these systems. So, going forward, I want to incorporate generation of bootable rescue cd's into my upgrade processes. Clearly, such a cd will exactly duplicate my last successful boot, and give access to ALL files and filesystems. [1] What is the simplest most reliable process for creating such a cd? [2] Upgrading WHICH packages should be followed by creating such cd? Obviously, upgrading vim itself is NOT likely to jeopardize my next boot; but, the kernel, some libraries, and some packages involved in the early boot stages, are possible culprits. What do you do? What do you think? It's very easy to create a GRUB boot floppy or CD. Just read the Installation section at: http://www.gnu.org/software/grub/manual/html_node/index.html At a minimum you are likely to need to update GRUB whenever you upgrade or install a new kernel, repartition, or add/change drives. Also, in an emergency there is a 64-bit version of Knoppix at http://www.applia.fr/contents/knoppix64.html that might come in handy.

I've seen the term before but don't understand exactly what COW means, but I think I know what you're talking about. I had a failing disk drive last Friday and had to boot my system off of a Knoppix disk to see what I could salvage from my raid-1 array. Knoppix didn't seem to include the smartmontools package but I was able to use apt-get to install it on the fly and use it to diagnose which disk was failing.

Re: rescue bootable cd ???
Hi It is also possible to use the install disk. You just stop after detecting the hard disk (don't reformat it :) Then you do: #mkdir /mnt #mount /dev/sda1 /mnt #chroot /mnt and then you can do whatever you need to fix your system. Hope it helps Gudjon -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

COW stands for copy on write, whenever a change is made to a block (or file maybe, I don't know what granularity unionfs uses) that block is copied somewhere else and the original left in place so that the update can succeed and the original still exists. Sort of like an LVM snapshot only instead of being backed by a LVM volume the changes are only stored in memory. But yea, the short answer is that it allows you to make changes and install software on read-only medium like CDs. =) Jim. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.
