FYI: you don't need a DRUPAL-6 branch to make a development snapshot
release that's compatible with 6.x core. just make a release node
and use "HEAD" as the CVS branch, set it to "6.x" core compatibility,

This is where the problem is.

I don't have 6.x listed. I only see None, 5.x, 4.7.x, and 4.6.x only in the select box.

So, I can't select 6.x.

and give it a major number of "1", a patch level of "x", and an extra
identifier as "dev".  viola, a 6.x-1.x-dev development snapshot from
HEAD.  then, whenever you make the DRUPAL-6 branch, you can just edit
this release node and you'll now have the option to move the CVS
branch from HEAD to DRUPAL-6.  no, you don't need any special
permissions on d.o for this -- anyone who can edit the release node
can move it from HEAD if there's now a CVS branch that doesn't have a
release node but that specifies the same version information.  after
that "HEAD" will again be an available choice when creating new
release nodes, e.g. for the initial 7.x port, or as a 6.x-2.* new
feature series.

so long as you give the HEAD release node a version number that
*could* someday be its own branch (i.e. major number >= 1), you can
always move a HEAD release node to the appropriate branch once that
exists.  see http://drupal.org/node/89699 for more.

someone should really update http://drupal.org/node/17570#HEAD with
this wisdom.  any volunteers? ;)\
