I also disable the paranoia file system checks, with â€œtune2fs -i 0â€³ and â€œtune2fs -c 0â€³. 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.Edited 2009-07-16 00:57 UTC 2009-07-16 5:54 am kragilFor 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. 2009-07-16 7:31 pm RahulThat’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. 2009-07-16 9:22 pm Bill Shooter of BulShe 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? 2009-07-16 11:57 pm LennieHave a look at this:http://kerneltrap.org/search/node/hammer(the site hasn’t been updated in quiet a while, but it has good articles) 2009-07-17 2:02 pm Bill Shooter of BulThanks! It will take me a while to digest all of that.
