Yes, so did I on my own node.  However, read the excerpted release notes included
at the end of this article to see a problem that isn't solved by
a simple `node_data link.

This is a fine idea.  Are you asking us to change something?
It doesn't seem like we need to change anything further so you
can continue to do this.

Here's an excerpt from the release notes going out on SR10.1.p and
SR10.2 describing how the new scheme works.  (caution; don't
use stuff you read on news as a reliable source for release notes,
but rather read the notes that come with your software, because this
stuff could still be changed at the last second).

"At SR10.1.p we are moving the location of the system color maps in
 order to allow diskless nodes to have different color maps than their
 paging partners.

"Prior to SR10.1.p, the system color map was stored in
 /sys/dm/color_map.  At SR10.1.p  color_map is
 stored in two directories:

       'node_data/etc/dm_display/color_map
 and
       /etc/templates/dm_display/color_map

"Note that /sys/dm/color_map remains as a link
 to the color map in the 'node_data directory."

"When a diskless node boots from a paging partner that it has not used
 before, the system software copies the color map in
 /etc/templates/dm_display/color_map into
 'node_data/etc/dm_display/color_map.

"You can then modify the color map for the diskless node by editing
 'node_data/etc/dm_display/color_map.

"Note that if the diskless node has used the paging partner before the
 system leaves the color map file alone.
