It seems to me that based on the fact that 'buildbot-slave' is a 
different package name I also think this is OK. It means that for 0.8.0 
we'll have:
* A 'buildbot' package which contains the master and the slave in the 
old layout.
* A 'buildbot-slave' package which contains only the slave, in the new 
style layout. We could even call it a beta of the slave-only package.

Then, for 0.8.1 we'd have:
* 'buildbot', which would master-only in the new style layout.
* 'buildbot-slave' which would be slave-only in the new style layout.

For 0.8.0 you could use either package on the slave. For 0.8.1, you'd 
have to use 'buildbot-slave'.

Just my $0.02.
