Hi Toshio,

[didn't we talk at a Mexican place after the fudcon in Boston?]

Using such a mirror need not be a one-way transaction.
Obviously, it'd be far less useful if there were such a limitation.

When I do serious work against an upstream CVS repository, I arrange to
mirror the CVS repo to git, and do all of my work in git, committing
changes on private git branches.  Then, I can easily rebase each of
those branches (sort of like cvs update), to synchronize with newer
upstream changes on the parent branch.[*]  When I want to commit to
cvs, it's easy to automate using git-cvsexportcommit.  While this MO is
not as comfortable as working in a git-only environment, it does help
give you a feel for what it'd be like, and *I* certainly appreciate it.
Of course, this can't help for tag/release-related operations, but it's
a good start for the rest.

Even with this slightly-contorted routine, I've appreciated using
git: for example, while using conventional diff, patch, and cvs,
it's easy to forget to "cvs add" a new file that was added by a patch.
It's also easy to forget to apply "chmod a+x..." to a script just added
by a patch.  But in git, that doesn't happen as much, because the tools
do more of the work for you.  And git-cvsexportcommit takes care of the
details of making sure everything in a git change set makes it back
into a cvs "commit".

[*] In case you haven't seen it yet, "git rebase --interactive" is very
useful, if you care about the "perfect patch" sort of process.
With it, there's no need for quilt/stgit/etc.
