Classy Lady

You've really got to admire this lady who is not only a brilliant filesystem developer, but has the guts to publically see the truth and tell it like it is, despite it being a violation of political correctness:

On my own systems, I always run ext3 with noatime or relative atime if it’s available. I also disable the paranoia file system checks, with “tune2fs -i 0″ and “tune2fs -c 0″. And I turn off SELinux, which uses extended attributes heavily as well as generally being a pain.

Oh, and she's a Red Hat employee! And I must say I agree completely.

For a dev box SELinux is just insane. It will get in your way.
I run F11 on my netbook and had only one tiny hiccup moving my home partition. I think by now Fedora has nailed SELinux for all general use cases. If you like to tweak a lot or develop stay away.

That's spot on. SELinux works pretty much out of the box in the last couple of releases. Keeping policy in sync with development versions however is a more tricky problem and on development machines, it is going to not so smooth yet especially so if you are working on a new filesystem like she does. Ideally, policy modules should be part of the packages instead of being in a separate central package. Atleast for user space, that would eventually be the right architecture.

She made a passing reference to Hammer FS from DragonFly BSD. I wish I could read a review of its design and implementation from someone of her impeccable credentials. Does anyone know of a good review of the FS from a neutral third party?

Thanks! It will take me a while to digest all of that.
