[quote=ucodegen]To avoid the bleeding/breaking, I tend to be about 1 rev behind the current… and can pick up ‘updates’ to fix the one installed. That is why I am running FC10 though FC11 is out.[/quote]

I used to do that too until I realized they swiftly cut off support/updates to old Cores after only a year or so. This is the ‘bitten in the ass’ to which I referred. So if you plan on using your machine for more than a year, I wouldn’t recommend Fedora Core unless you’re cool with doing a full system update every year (which isn’t always possible in some environments where downtime is a no-no).
