[tex-live] svn vs. p4

    svn writes some meta data even if nothing has to be updated.

svn status does not write anything.

I definitely agree that the first svn status (or update) takes longer
than subsequent ones, and the obvious reason would be disk caching.  I
don't know how to prove it.  Whatever.

Anyway, the general whole-repository update doesn't need to be done very
often.  Once or twice a day from cron should be enough.  It's doing
updates that I'm more concerned about.  40 minutes to update LM is a big

    The .svn files in the ls-R databases might
    slow down things as well 

They won't be there, of course.  I think I already checked in changes to
exclude them.

    It would be a pity if we decide to use svn now and it turns out
    later that we cannot have binaries for old systems because of
    hardware limitations.

I don't understand.  What does svn (or p4 or whatever) have to do with
what binaries can be supported?
