Git submodules are roughly equivalent to svn:externals with peg

the state that is checked out will be the same for everybody.
Please take into account however that submodules are quite new
feature, and while underlying engine is solid, interface (UI) needs
some polishing (and use cases).
There is one facet of submodules that annoys me, because it prevents
me from using them as a replacement for svn:externals. Namely, the
submodule refers to a specific repository, but not a path within that
repository. I work with svn repos that use svn:externals to peg
revisions (as is appropriate) but they all refer to various paths
within the other repositories, and the only way I can deal with that
is to throw symlinks everywhere.
I don't quite understand. At the lowest, "gitlink" level submodule
entry is just having _commit_ object in place of directory. And of
course this commit object refers to top tree (top directory) in
a subproject.
If you have subproject B with the following file structure
B/foo
B/bar/baz
and you have (super)project A, which contains B as subproject at path
sub-b, and has some files itself, the directory sytucture would look
like this:
A/quux
A/sub-b/foo
A/sub-b/bar/baz
What you want, I guess, is some a bit weird for me mixture of
submodule
and partial (subtree) checkout... and the latter is not implemented
yet
(I say "yet" because there was some preliminary implementation of
subtree checkout on git mailing list).
It seems you understand what I'm saying. The only way I can mimic it
is to make the submodules actually live in some hidden directory .foo
and then scatter symlinks everywhere.
