Using rsync filter to include specific, deep subdirectories under source path?

First, don't use rsync without either --times or --archive.  Without
one of these rsync won't have any idea what is different the next time
it runs and it will re-copy everything.

As for the problem, if a directory is filtered then rsync will not
look inside of it to see if there are any not filtered things inside.
 Therefore, if you want to specify /boot/grub you need /boot too.

The other alternative (and easier way) to handle multiple directories
is to add --relative and list your directories instead of sources.

IOW: rsync ${ROPTS} --relative root at my.remote.com:/boot/grub/
root at my.remote.com:/boot/grub2/ /home/TEST
