A very userful rsync patch is missing. The --copy-devices patch, which can copy raw device contents over the wire (like for backup whole hard drives), the opposite of --devices.
No other application on portage tree can do that straightforward.
The patch (already in Fedora since 2009): https://bugzilla.redhat.com/show_bug.cgi?id=494313

Patch for rsync 3.0.9
The easier patch shortcut (clean).
More handsome rsync patches here:
verified working. definitely recommended to add.
Patch needs s/a\//a\/rsync-3.1.1\//g and same for b/. Not sure if there's a Gentoo way for oneshot application of a patch that diffs just a/file.c
Is there any blocker moving this forward?
Note that write-devices patch would also be needed to do the reverse.
