The tight linkage is absolutely essential. When we tag the system, we want to tag everything (not individually tag all 300 programs) so that later we can to branch at that tag. Very few of our programs are self contained, they generally make heavy use of one or more libraries --- which must also be part of the tree. The full structure should end up looking like: Top/.git Libraries/libx Libraries/liby Libraries/boost Libraries/... Programs/xxx Programs/yyy Programs/... ...etc. When we build a full system, we want to tag that point so we can know exactly what went into that build. We used to do it the "other" way. cvsroot/xxx cvsroot/yyy cvsroot/liby cvsroot/libx etc But then when we did a system build, someone always forgot to tag something. So we got cvs to build a build logical tree and then cvs was quite happy to tag the lot with one go and nothing got forgotten. So now we are trying to pull the lot into git as one big tree.
