Yet it runs just fine under iBCS emulation on Linux...

So write support for these, however...

Have no idea what you mean. raw devices work just fine on Linux, tar -xvf /dev/fd0 for instance? Works fine. If Oracle needs raw partitions, no problem.

Then the whole internet is flakey, since Linux runs on more servers on the net than anything else. Rock solid is more like it. It runs just fine under iBCS emulation on Linux...

You're thinking of (an old version of) SunOS :-)

It's actually not that bad in 2.1 I hear, and I fail to see how that affects the viability of Oracle on Linux.

But it works fine under iBCS on Linux. Interesting. You're mistaken.

That may be so, but it has nothing to do with weakness in Linux. I suspect it has to do with Oracle's relationship with the Big UN*X Vendors.
