Systemtap 1.0 has been released. There are a few features for this release, like experimental support for unprivileged users, cross-compiling for foreign architectures, matching C++ class and namespace scopes, reduced runtime memory consumption, but more importantly, this release means that Systemtap is finally considered stable and ready for user adoption.

Is it really? For years I have watched as the Linux users complained as Solaris users pointing to tools like DTrace and ZFS as reasons to select Solaris over Linux.
From the FCS (3/05) release of Solaris 10 which had Zones and Containers virtualization capabilities "out of the box", it took RedHat and Novell 18 months to package virtualization capabilities in their respective products. And while RedHat and Novell have added some virtualization tools, there is no way to create a Container or a WPAR with either product. This is so they could stay competitive with Sun, IBM and HP.
The same goes with DTrace over Systemtap, why does it take Sun, IBM, HP or insert your vendor of choice here to produce some "cool tech" before someone thinks that "wow, maybe Linux should do that too". I have said it before and I will say it again "Where's the innovation at?" Because that is what it looks like when you start comparing feature sets of the various OS's. While imitation is the sincerest form of flattery, at some point it stops becoming imitation and starts to look like copying what others are doing.
If Linux was "bleeding edge" it should be the other way around, Sun, IBM and HP would be trying to get the "cool tech" from Linux and that's not the case. And while people here might not like Kebabbert's opinion of the state of Linux feature development, what has he said that isn't true?

... Don't know, maybe Linux users actually need a copy-on-write FS? Performance gathering library? Maybe they actually need container based virtualization solution? Should RedHat simply give up on giving their customers what they need simply because it doesn't measure up to your "innovation" standard?
Oh, lets not forget, if Sun starts following your "innovation" standard they should stop working on porting VirtualBox (which they own) to Solaris - after all, VMWare had it first!
Has it ever occurred to you that having a better, faster, more-resilient ZFS in the form of BTRFS * is -far- more important than your "innovation" factor? (In my short experience with ZFS, if something happens, good luck trying to salvage anything)
In end, I'd imagine that most users don't really care about "I got there first" pissing contents - they (should) only care about what works, and works well. Who invented it first is irrelevant.

I'm say that I'm baffled by your post.
So, if Sun has dtrace, Linux must not have it's own system performance gathering interface? Assuming that Linux cannot use ZFS due to licensing and design problems, should they stick to ext2? (ext3/4 has a journal, someone must have had it beforehand...)
Should Intel drop vtune just because Linux has oprofile? (or vice versa)
What's next? should the GNU people stop working on GCC just because Watcom came first?
Where does it stop? Browsers? Editors?
Heck! Lets kill Linux! Minix came first!
... You do understand that how ridicules and childish your copycat claim sounds, right?
