No, cvs-fast-export does not have --export-marks. It doesn't generate the SHA1s that would require. Even if it did, it's not clear how that would help.

Confirmed.  Looks like ibiblio is having a bad day.  I'll file a bug report.

That's the "stability" property that Martin Langhoff and I were discussing earlier.

cvs-fast-export conversions are stable under incremental lifting providing a commitid-generating version of CVS is in use during each increment. Portions of the history *before the first lift* may lack commitids and will nevertheless remain stable through the whole process.

All versions of CVS have generated commitids since 2004.
