Hi Henrik, another question: If I set a variable twice in the config file, e.g. ofs.osslib, will the value get overwritten?

In this activity I have based my modules and templates on the ATLAS US Tier3 puppet modules. I am by no means an expert on puppet, but I do have some experience crafting puppet modules and templates for different services. I have some spare time right now, so if you'd like me to take a look at your specific setup let me know. >>>>>>>> >>>>>>>> Best regards, >>>>>>>> Henrik >>>>>>>> >>>>>>>> >>>>>>>> -------- Original Message -------- >>>>>>>> Subject: Anybody with puppet for xrootd ? >>>>>>>> Date: Wed, 15 May 2013 16:09:38 +0200 >>>>>>>> From: Fabrizio Furano <[log in to unmask]> >>>>>>>> To: xrootd-l <[log in to unmask]> >>>>>>>> CC: Martin Philipp Hellmich <[log in to unmask]>, Oliver Keeble <[log in to unmask]> >>>>>>>> >>>>>>>> >>>>>>>> Hi xrootd folks, >>>>>>>> >>>>>>>> as DPM team we are planning to invest into puppet for the setup, and >>>>>>>> of course this would cover also the so-called xrootd plugin, that >>>>>>>> involves an xrootd setup as a frontend of DPM, plus some DPM-related >>>>>>>> Xrd* plugins. >>>>>>>> >>>>>>>> The question is... is there anybody who has experience/templates/etc. >>>>>>>> about setting up xrootd clusters with puppet ?
