I don't think ksplice changes things -- it seems to only work for very
minor kernel patches.  For example, any change to the layout of a
kernel structure would appear to be incompatible with ksplice.  Thus
it seems highly unlikely it'll ever work in its current form for
arbitrary kernel revisions.

Trying to ksplice from 2.6.29.4 in the installer to say 2.6.30.1 or even
to 2.6.31 does sound like massive fail...


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.

peace...
