I've been thinking about rewriting that patch so that the creation time
is sent as a time attribute, like the atimes patch, instead of going to
the trouble of faking an xattr value. This has several advantages,
including only needing a single call to read the value, and also it
might avoid the creation of so many separate xattr objects for the
various files. The patch for this is now a patch/crtimes branch in git,
and can also be seen here:
http://rsync.samba.org/ftp/rsync/patches/crtimes.diff
This requires the use of a new option, --crtimes (-N -- think "newness")
to get the create times preserved. If you want -N anytime -t is used,
you might want to add a couple popt aliases to your ~/.popt (or even
/etc/popt) file:
rsync alias -a -aN
rsync alias -t -tN
