Please provide some information regarding this issue.
I have read that the kernel is interrupt driven rather than schedule driven. If that is what you mean, all linuxes are real time.

Thats not generally enough for many peoples definitions, which is that the time to respond to an (external) interrupt is fast, un blockable, and well defined.

I realize there are many definitions. However what you suggest is what "nice" is for. Having a real time OS and tailoring it are two different matters.

If you think of how many ways to stop your 'lunix' responding to a keyboard interrupt exist, you will get my drift.

Change the BIOS to no keyboard? Or something like that. The keyboard is not a linux function. It only reads the BIOS.

Most RTOSes are very lightweight and very carefully controlled in terms of response time to interrupts.

I have never become involved in tailoring a OS compile to single applications. I have no idea how to do it. I have READ killing all the unneeded material is possible.
