18632RE: [nslu2-linux] Re: Howto substitute the kernel _safely_
- May 1 11:36 AMPhil, thank you very much. You clarify me a lot, but
* Is there any page in wiki that content this?
* How can I use upslug2?
* If I compile kernel ala debian, debian could update my kernel in apt-get upgrades?
* Where I can find the configuration file of original kernel (in which there are all the modules and built-in that kernel have compiled to)?
Thanks in advance,

1. Make a copy of the entire contents of your flash:
cat /dev/mtdblock* > flash_backup.
2. Move that to another machines.
3. Try out your new kernel.
4. If it works, good! Stop here.
5. To return to your original kernel, use upslug2 to restore the image
that you saved before.
There are other ways to solve the problem, but this is by far the
easiest in most cases.
