Then I fail to understand the difference between the effects of native CVS branching and SVN branching with subsequent export into CVS, from the point of view of cvsup: > > > SVN metadata changes will appear in CVS as version changes only.

In both cases, the affected files are touched, changed and downloaded by cvsup, i.e. we have a massive download of all files after branching. But to hell with this. I started the topic because I think something is wrong with SVN to CVS export, which upsets cvsup and causes "Checksum mismatch" errors.
