Re: Making NPTL the default for FC3, vanilla i386 support

It's always a bit sad to have to give up compatibility, but otoh most
boxes with i386 CPUs (including Cyrixes and WinChips) are usually not
that well equiped to run the bloated releases we have today anyway.

Actually i386 support has already been effectively discontinued
(https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=103078). Time to
start looking for some small footprint distros for such boxes.

Well, at least one person has tried to :) .

Although it might appear a bit funny at first I think this is the most
consequent solution. If it's not i386 compatible it shouldn't be called
so.

Also have a look at
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=91933 .
