I thought it was `2.2.8-RELEASE or later', not `the latest
2.2-STABLE'. (I know this has been stated regularly in various
mailing lists, but I can't find the exact wording in the FAQ or
handbook). AFAIK, this recommendation was more along the lines of
`it's known to work with 2.2.8 and isn't guaranteed to work with
earlier releases'. I'm fairly certain I've upgraded machines from
2.2.6 or 2.2.7 to 3.x without installing 2.2.8. If we implement this
change, it will be `the upgrade is guaranteed not to work unless you
are running 3.x from 1st October 1999 or later'.
I believe that the above also implies that there should be a
3.4-RELEASE before 4.0-RELEASE (I'm not sure what has been planned)
so that there's a -release that is upgradeable to -current.
In any case, I'm not sure that this is a particularly clean solution:
1) It is a specific work-around for this problem and does not solve
the general problem: Buildworld should not use be using tools
built for the new world with the current kernel.
2) It's not a change that can be applied to -current, tested and then
MFC'd. This increases the likelihood that it will break -stable.
