FWIW, PDSF.nersc.gov uses it.  Maybe you could ask someone there for
their experience.

On my own little cluster I use something called "usepackage"

  http://sourceforge.net/projects/usepackage/

It's also in Debian, maybe others, but it is easy to build from source.

One nice thing I like about usepackage is that you can have a
decentralized set of package environment definitions.  I use this to
create definitions for each experiment or group that uses my cluster and
then individual users can include whichever ones matter for their own
account.  It also lets me manage different releases of an experiment's
code.
