Simple UI question...

Hey guys,

So I'm trying to figure out the best way to pull out a checkout of the entire tree as of a given revision ID. I have a whole bunch of revision IDs, and I'd like to know what the git equivalent of (say) the following is:

svn co -r280600 file:///path/to/svn/repo

For the sake of argument, let's say that r280600 imported as 07058310db903317faa300b93004a5a2e0fc2dcc into my git tree.

How do I get a pristine checkout in my working copy of the entire tree as the repository saw it at 07058310db903317faa300b93004a5a2e0fc2dcc?

Eric Anholt suggested 'git checkout -b temporary-branch-name $sha1sum'; davej suggested 'git-read-tree $sha1sum && git-checkout-index -a -f' but for some reason, neither of these commands seems to do exactly as I expect. davej's method seems to work for some revision IDs, but not for others, and the other method seems to work just about as well. (The problem I have seen is that, for some revisions, the only files I get in the working copy are the files that were changed in that commit; the rest of the files in the tree do not get checked out.)
