I agree completely. My point is that as of right now, there is a large
degree of collisions that take place, that prevent an install of
6.3-RELEASE and 7.0-RELEASE from existing at the same time on the same
drive, and being trivial to switch between the two if need be. Same as
This is an artificial construct, and doesn't /have/ to continue
existing. Which imo, will be far more useful then expecting a large
amount of time expended to dead-end branches of code that are well
past their expiration date, and begin suffering from massive bitrot.
At the very least, it will make the default system more robust by
moving the majority of the upgrade procedure from being /replacements/
of files, to creating new files coupled with an atomic activation
Please don't misinterpret my ideas as being supporting his viewpoint,
