I would wonder if they were, but they're clearly not. Corporations love Linux. It's less expensive and commodity. It frees them from expensive proprietary hardware vendors (Sun Sparc, HP Itanium, etc.) and lets them find the right x86/x86-64 servers for them. They can use free versions (e.g., CentOS) in some environments and paid enterprise versions (e.g., RHEL) in others. Most of the big enterprise packages (Oracle, DB/2, Websphere, JBoss, SAP, etc.) are available in Linux. The enterprise data center is a war between Linux and Windows (with the mainframe, AS/400, and other monotowers, though they are rarely growing).
The "SCO scare" is a thing of the past. I can tell you from personal experience after many years in the infrastructure world that the license headaches with Linux distros are nothing compared to the eternal headaches that I've had with companies like Veritas/Symantec, Oracle, etc.
Most of the decision-makers, technical architects, etc. in corporations do not operate at the "why ZFS is better" level. Does $LINUX_DISTRO support RAID, SAN multipath, and other common enterprise storage needs? Great. That's all we need. Frankly, while ZFS is great, it's not enough of a game changer to make someone buy Solaris over Linux.

Rather, you'd be much more interested in a real-time OS that is compact (so that most of the memory can be used for double-buffering the video and buffering the network traffic and disk activity) and supports only the absolute key features you must have. In the end, it is cheaper to develop a few minor features for an OS kernel than to test a horribly large number of pathways, and for something like TiVo, users aren't going to care about the 99.999% of the time it works great, they're going to remember and whine about the 0.0001% it doesn't.

Eh. Sun intentionally chose the license to be GPL incompatible.
And it's quite likely that their explicit intention was to be Linux incompatible as well. Should it have been licensed under some other terms, the license for ZFS would likely have been chosen to be incompatible with that. For instance, if Linux was BSD licensed, Sun could have just released ZFS under the GPL. While in theory it's perfectly compatible, in practice a BSD project will refuse GPL patches.
Which really makes sense, as Linux has been replacing Solaris in lots of places, and I imagine Sun didn't want to help them with that.

For most people, ZFS is a cpu-sink that offers slightly more convenient volume management, at a high price for hardware overhead and latency.
But you have to use it on solaris, because their UFS infrastructure is so out of date, you can't support a reasonable number of spindles (without investing even MORE money in moving that problem off the box entirely).

Sure, there are other "non-current" linux developers/maintainers, and there are many others who have been doing the job in the past. But that's an entirely different development model than the 2.6 tree has been, and there's nobody who "fills in" for Torvalds when he wants to take a break. The man is 40; he's going to have to slow down sooner than later. He's certainly not keeping up his percentage of code commits, nevermind the level of code (though the quality, quite possibly). He's got 3 daughters and a wife; the man has to sleep at SOME point.

1. User-space scheduling. It would be nice if a process could have better control on the priority of each of its threads. For example, on a web service where multiple users are active, it is often necessary to give each user his/her share of the cpu. Right now this is rather difficult to do in a fair way, since multiple threads may belong to the same user.

2. Recursive strace: Currently it is not possible to run "strace" on a process which is already being straced. So for example: "strace -f strace -f ls" will not work (you'll get an "operation not permitted" inside the first strace. This makes it impossible for programs to use strace (or the related ptrace system call), since other programs which might also use strace, may depend on them.

3. "Nice" for bandwidth. It would be great if there was a command similar to "nice", which acts not on cpu-cycles but instead on bandwidth.

4. "Select" or "poll" with access to inter-thread synchronization structures. Select and poll are system calls which act mainly on file-descriptors. However, sometimes you'd like to wait also on a mutex or semaphore. Some support for this would be great.

Isn't this what pthreads condition variables are for? Or can you explain what you want in more detail?
The main point is that it is now not easily possible to wait for both a file and a mutex, for example. A workaround could be waiting for a pipe, and writing to the pipe in a separate thread, but of course, this may become hairy.
From a user-space programmer's perspective, it would be nice to have the synchronization objects and file descriptors in the same id-space, but perhaps a simpler solution is possible.
Btw, thanks for the pointer to cgroups. I'm not sure if it entirely matches my needs, but I'll look into it.

Eh. Sun intentionally chose the license to be GPL incompatible.

This keeps being said. Do you have a source for this?
