Yes, I was only really referring to the 'idea of ksplice', not it's 
actual implementation thus far.  Or rather, more in an enterprise/LTS 
scenario like that company dedicated to supporting an extremely stable 
set of ksplicable kernel packages.

Because in the fantasy scenario, with such ksplice, and 
RebootlessInstaller, a truly rebootless OS lifecycle does become 
theoretically possible.  Which is kind of cool.  But that is so bleeding 
edge it really shouldn't distract from the current decision on this feature.
