Gentoo is a great distro for customization. When you're done with the install, you don't even have X

Speaking to the OT, I find that every time Ubuntu comes out with a new LiveDVD, they add new bugs and don't fix old ones. The more they try to do, the more they break. Examples:
-Sometime in '06 they decided to start supporting Bluetooth out of the box in the LiveCD environment. That's all well and good, but don't switch my Bluetooth hub from HID to HCI without bothering to reconnect my peripherals. And yes, I know there are ways you can do that manually, but if said peripherals are your keyboard and mouse, you kind of need said peripherals to connect said peripherals...
-Besides the Bluetooth input devices, I hardly have what any would consider an exotic setup. Yet for some reason right before GDM starts, my screen goes black. The only way to get it back is to <Ctrl> <Alt> <F1> and then <Ctrl> <Alt> <F7> back to the login screen. I'm guessing this has to do with their more aggressive support of video adapters, all in the name of an accelerated desktop in a LiveCD environment.
-Fakeraid is broken. RAID0 and RAID1 work with many onboard controllers, but if you attempt to initialize a RAID5, dmraid looks for a deprecated kernel module. This isn't actually an Ubuntu issue; it seems to affect all distros.
Right now I'm running Gentoo on my desktop and Vista Business on my tablet. Both are great operating systems, and I love them both for different reasons. At the end of the day, however, I prefer Vista, but I'm sort of stuck with Linux for now since I have 100s of GB of data in a software RAID5. My plan is to someday spin off the array into a headless fileserver and use Gentoo for that, and put Vista back on my primary desktop.
