On pianosa: The ezca.Ezca class somehow initializes with its prefix set to "C1:", even though the docstring says the default is None. This makes existing scripts act wonky, because they're looking for channels like "C1:C1:FO-BLAH".
In ligo/apps/linux-x86_64, I ran ln -sfn cdsutils-old cdsutils to get the old version back for now, so I don't have to edit all of our up/down scripts.
Also, Chiara can't find the epics package when I try to load Ezca. It exists in '/usr/lib/pymodules/python2.6/epics/__init__.pyc' on pianosa, but there is no corresponding 2.7 folder on chiara.
I just pushed a fix to ezca to allow for having a truly empty prefix even if the IFO env var is set:

In : import ezca
In : ezca.Ezca()
In : ezca.Ezca(ifo=None)
In : ezca.Ezca(ifo=None).read('C1:LSC-DARM_GAIN')
This is in cdsutils r232, which I just installed at the 40m. I linked it in as well, so it's now the default version. You will have to make a modification to any python scripts utilizing the Ezca object, but now it's a much smaller change (just in the invocation line):
-ca = ezca.Ezca()
+ca = ezca.Ezca(ifo=None)
