No, not confused on that point. We just will not be testing OS versions at the 40m or running multiple OS's on our workstations. As I've said before, we will only move to so-called 'reference' systems once they've been in use for a long time.

True - its an issue. Koji and I are updating zita into Ubuntu16 LTS. If it looks like its OK with various tools we'll swap over the others into it. Until then I figure we're best off turning allegra back into Ubuntu12 to avoid a repeat of this kind of conflict. Once the workstations in the LLO control room are running smoothly on a new OS for a year, we can transfer into that. I don't think any of us wants to be the CDS beta tester for DV or DTT.

Just to be clear, since there seems to be some confusion, the SVN issue has nothing to do with Debian vs. Ubuntu.  SVN made non-backwards compatible changes to their working copy data format that breaks newer checkouts with older clients.  You will run into the exact same problem with newer Ubuntu versions.

I recommend the 40m start moving towards the reference operating systems (Debian 8 or SL7) as that's where CDS is moving.  By moving to newer Ubuntu versions you're moving away from CDS support, not towards it.
