Stability

I always look forward to reading my issue of LJ each month. Great magazine; thanks.

The reason I am writing is to share a concern regarding Linux API stability. I enjoy system work too, but the fact is my company sells applications, not operating systems. If I am to produce shrink-wrapped applications, user and kernel APIs must remain stable. I just worked my way through our several drivers to get them from 2.0.* to 2.2.* series kernels, and now I see the driver API is changing again in 2.3.*. It is a terrible temptation to keep improving, but if it works, let's leave it for a while. And maintaining old APIs is not a long-term answer either—that's what makes UNIX systems so fat, all the baggage they carry around.

Thanks for listening.

As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.
