extensions don't matter in linux. they could be called foo.bar.fred.joe. doen't matter. Linux is no different that Unix when it comes to file exensiions, there are suggestions and habbits people use, but beyond that, it doesn't matter.
so wait. let me understand exactly what is going on here. "may not support redhat 7.3" doesn't really tell me anything...
you are using etlinux, which is an embeded Linux distro.
you load the kernel, it boots and drops you to a command line...somewhere in this there are all sorts of errors with your rc files loading (the kuzu message, btw you couldn't have picked a much more random and useless error message to copy
). After all those error messages you see something like
and you login and start typing away at the keyboard....either that or you set it up to boot to X, in which case there are probably more errors.
What is more than likely happening here, is the precompiled kernels don't support some part of your system, be it file systems, sound cards, etc..
If you asked me where to put my money, I would say: "You clicked through the Redhat 7.3 install. Redhat used the filesystem ext3. The new kernels you are tying out don't support ext3, which so happens to be supposedly backwards compatible with ext2, but it really breaks stuff."
Now, I read through etlinux's website, and maybe you can explain to me, Why are you changing the kernels? in preperation of the "host" system, all you need to do supposedly is:
While I'm working with embedded XP right now (at a slave's wage), I haven't delt with Embedded Linux...What is it that you are trying to do exactly, I think you might be walking down the wrong path for some reason.
