I'm absolutelys with you in this point. Method 2 needs much more effort to
keep track of vendor libs and bears the problem of keeping track of them in a
central location.
If all devel projects use one vendor/internal lib repository via externals
it's easy to check/control which projects use which libs. You could just only
provide read access to exactly one lib so there is no way that different libs
are used by different projects

Well I don't intend to store a complete drive-image in the source repository
because of it's binary sizes - although I like the idea in some way.
What we do is getting the test- and build-system specification in a text file
(build log) and save this in the repository. Of course this doesn't work for
all kinds of development (for the Java platform it's quite OK I think)

Cheers,
Reinhard
