an extension of AIX to support high-end hardware. AIX 5 has the best of
Monterey. Linux cannot fill that need today, but over time we believe it
will. To help out we're making contributions to the open source movement
like the journal filesystem. We can't tell our customer to wait for Linux
to grow up. They need solutions today.
So if Linux grows up, will you abandon Monterey?
You're speculating that if all were equal, I'd rather be on one OS
than the other. There are always customers that have written software for
AIX API's and might want to use the capabilities of Monterey. We're trying
to make they co-exist. We're trying to allow customers to write to Linux
API's that run on top of a Monterey based OS.
What about the other way round? AIX apps running on Linux?
Yeah. If Linux had all of the capability of AIX, where we could put
the AIX code at runtime on top of Linux, then we would.
Are you doing anything?
Right now the Linux kernel does not support all the capabilities of
AIX. We've been working on AIX for 20 years. Linux is still young. We're
helping Linux kernel up to that level. We understand where the kernel is
is. We have a lot of people working now as part of the kernel team. At the
end of the day, the customer makes the choice, whether we write for AIX or
Will AIX be open source?
We're willing to open source any part of AIX that the Linux community
considers valuable. We have open-sourced the journal filesystem, print
driver for the Omniprint. AIX is 1.5 million lines of code. If we dump
that on the open source community then are people going to understand it?
You're better off taking bits and pieces and the expertise that we bring
along with it. We have made a conscious decision to keep
contributing. There are some things that the Linux community can do
better. Linus is worried that there is too much code in the kernel and
it's taking longer and longer to get a new release out. So, we could open
source AIX but it is just not practical.
