In article <20030424141111.GN18587@mewburn.net> you write:

Ugh.  "alpha" to me implies a test release, i.e. that there will be no more
features added before the final release.  It's also bad in that you have to
distinguish between NetBSD/alpha 2.0 and NetBSD 2.0_ALPHA.

>once 2.0 is released, the netbsd-2-0 branch is ID-ed as "2.0_STABLE".

If you're going to have "_STABLE", how about "_UNSTABLE" to go with it? 
That would have the rather silly effect of making this list
<unstable-users@netbsd.org>.
