Not necessarily GA but yes, it's a lot of additional work and a struggle
to fit this to the normal approach to kernel updates in Fedora.

To be honest, I'm glad to have the ksplice tools in the distribution as
it makes it easy to play with them if you're interested in the
technology but I do think that the applicability of this tool to a
distribution like Fedora is probably a lot less than it would be for
e.g. one of the "enterprise" distributions for the simple fact that end
users who are particularly intolerant to reboots are likely already
looking for a platform with a longer release and support cycle and
stronger (i.e. commercial) support guarantees.

Fedora users who just want quicker reboots can always make use of kexec.
Along with the boot time improvements in recent releases that should
make installing and booting a new kernel pretty quick (apart from the
inconvenience of shutting down applications).
