Tim,

Currently, the only thing which uses NodeJS in Openstack is the embedded
version of the less css "compiler". That one is normally stored in
openstack-dasboard in /usr/share/openstack-dashboard/bin/less/lessc. But
in our Debian package, this isn't a file, but a symlink to
../../../../bin/lessc. This symlink target, in Debian, is in the
node-less package, which contains #!/usr/bin/nodejs (as requested by the
Technical Committee). So everything seems fine on that ground.

What was missing, IMO, was a dependency on node-less in the binary
openstack-dashboard. I have corrected this problem and added the
dependency. Thanks for making me do that! :)

Please do check again if Horizon works *with* the node-less package and
*without* the nodejs-legacy package install, but IMO it should (it does
for me).

Cheers,

Thomas Goirand (zigo)
