Outch! Indeed, this is a Debian policy violation, as users should be 
able to mount /usr as read only! I hope that a symlink to 
/var/lib/horizon will be enough to fix this non-sense.

That's fine to me, Roland disabled the nova-volume service in the 
default nova.conf, so that nova-api doesn't bind on the same port as cinder.

BTW, moving from volume to cinder will be painful for our users. The 
client API remains the same and is fully compatible, but I have read 
that nova-volume and cinder database aren't compatible. I guess if some 
want to switch from nova-volume to cinder, they'll have to do that 
manually somehow. There's few threads on the subject which can be found 
on the web.

Indeed, we should remove any embedded library. When you write "lessc", 
are you talking about "lesscss" from lesscss.org? What's going to be 
painful is that NodeJS was not accepted in Wheezy, because of the "node" 
binary conflicting with the amradio package in Debian. The issue was 
opened for a year, until the tec commity decided that none of nodejs nor 
amradio should use "node", which is too generic. Then as the bug was 
opened for a year, NodeJS never migrated to testing. So if we want 
Horizon Folsom version to work with Debian Wheezy, we'll have to take 
care of these backports...

Now, about your patch, I don't really understand it. Why doesn't 
os.path.join(BIN_DIR, 'less', 'lessc') lead to /usr/bin/lessc? What's 
the value of BIN_DIR when the script is executed?

Anyway, when testing, we'll remember your patch. Thanks for sharing it.
