The title may be a wee bit misleading, but I don't see anything other than your post mentioning anything about a "hole".

The ghacks story that is linked to just cites engadget as a source... who don't mention *anything* about it "permanently modifying" the MicroSD cards, just that the manufacturers and microsoft are requiring that the cards are certified.

You're probably thinking of when CK gave up kernel hacking back during the Staircase Deadline days. That was /many/ years ago, though, and his ventures with BFS signified him picking kernel hacking back up.

Con Kolivas is still actively working on BFS, it's not unsupported. He's even got a patch for 2.6.36, which was only released on the 20th. http://ck.kolivas.org/patches/bfs/ He's also got a patchset out that I use on all my desktops which includes a bunch of tweaks for desktop use. http://www.kernel.org/pub/linux/kernel/people/ck/patches/2.6/

It's just horrifically out of date. If you're talking about Linux as in things that are generally applicable to all Linuxes, the Linux Documentation Project (http://tldp.org/) is actually quite well written... but almost everything is uselessly out of date. Most of the articles I've needed in desperate hours of trouble are still written for the 2.4 kernel series. This was especially painful when I was looking into software RAID. There's some great stuff in TLDP, but it's all outdated. At this point, I think gentoo-wiki and ArchLinux's wiki are some of the most helpful places to go if you're using anything that's not .deb or .rpm based.
