be, but all that is documented. And of course default packages are going to be different. Fedora ships with SELinux installed and enabled by default along with some other 'hardening' software to make things more secure by default. Just be aware of that, as SELinux is known to be a little too
strict sometimes and may interfere with some software.
SELinux is a PAIN!!!!! OHHHH I HATES IT! I think that's all it really comes with for the most part though, that's all I disable. boot peramater is selinux=0? Oh I could check my grub config, it's something like that. There is also a config file somewhere on the system too.
Anyways, I'd say the biggest thing is that debian tends to be a little less "fresh" than Fedora. All in all, they are both pretty good and solid. Speed wise, Fedora has caught up a lot and so I'd say they are almost equally good. A few minor things here and there between the two but otherwise Shrak's right. Mainly package management.
If you get into kernel/building custom packages (I like it, better than "make install" as it's easier to clean out later) then you'll notice a huge difference. Debian has more automated solutions for making packages from source. Better? Ehhh, depends. That is also still package management.
One other thing is Fedora has a very nice installer, though I believe Debian upgrades better. I'm speaking pure Debian, not Mint/Ubuntu derivatives (Ubuntu is pulling away more now, as it's actually using custom software instead of re-packaged debian stuff). So in that sense, I've never had a problem doing an update when debian moves releases around. I haven't with Fedora either but I've only done one update. I've read Anaconda isn't the friendliest nor is the package manager when a new release hits. But I also use Testing/Sid in Debian soooooooo....
Just expanding a bit on the differences that to me that are large ones. Oh and Debian is generally behind in kernel releases, Fedora isn't but that generally doesn't affect many people. Unless you have hardware specific bugs.
