Try telling your SAN vendor that you're running "just Linux" and can you have a driver and support package for that please, and let us know how you get on.

When you're done there, now try plugging your nice new machine into the corporate DC. Oh it seems it needs to support VLAN tagging. No problem, better just write some new code for that.

Time to migrate a bunch of performance sensitive services. Uh oh, no support for FusionIO PCI SSDs! Better write some more code.

Time to migrate your remote sites, only policy dictates certain services must be physically encrypted. No problem, better just cutpaste Debian's cryptsetup scripts and be done with it.

Oops, turns out we deployed 1000 machines with a duff BIOS setting. No problem, I'm sure the server vendor has a support package for CoreOS..

We could come up with examples until we've basically reinvented a modern Redhat/Debian initramdisk and boot environment.

There are certainly environments where enterprisey vendor testing and certification makes sense; mostly small or heterogeneous environments. But at large scale it's cheaper to do stuff yourself.

Also, CoreOS has more of a read-only stateless philosophy, so I think it'd still be interesting even if it ends up having to duplicate a lot of effort from mainstream distros.

That would have been a problem with every new distribution, including RHEL and Debian when they were brand new. In reality, your SAN should be able to accommodate a generic Linux kernel with any userland you can containerize.

Yes, and ideally Microsoft Windows should be open source and IBM OS/360 would have a build supporting Firefox running on my Nexus One, but that's not how the world operates..

Your sarcasm is tedious. If a SAN cannot support a generic Linux kernel, then it's the fault of the vendor for not allocating enough dev hours to the Linux kernel, and their product should not be chosen for a Linux environment.
