Re: Efficient way to import snapshots?

Aha!  I didn't know that you could point to a repository with GIT_DIR
and do useful operations without a working directory.  My "master" repo
that gets backed up and cloned everywhere is a bare repo anyway; I had
been cloning it with -s and then using 'git push' to get changes back
into it.

A couple questions on that:

1. Will it notice deleted files?
2. How can I tell it what branch to commit to?

You'd have to make sure that you have the CVS directories ignored, of 
course, and if you don't want to change the CVS directory at all (which is 
a good idea!) you'd need to do that by using the "ignore" file in your 
GIT_DIR, and just having the CVS entry there, instead of adding a
".gitignore" file to the working tree and checking it in.

Not a problem, I'm using cvsup in checkout mode so there are no CVS
dirs.  The checkout directory is an exact snapshot of "What The
Repository Should Look Like."

The above is totally untested, of course, but I think that's the easiest 
way to do things like this. In general, it should be *trivial* to do 
snapshots with git using just about _any_ legacy SCM, exactly because you 
can keep the whole git setup away from the legacy SCM directories with 
that "GIT_DIR=.." thing. 

I'll make a backup of my repo and give it a try.

Thanks!
