It is true, but let me explain a little bit so you see what I mean by *harder*. The part about Windows locking files that are in use is true, but MSI forces the processes to exit, so the files are no longer locked (but Puppet is no longer running either). The thing you may not realize here is that Puppet exits abruptly mid-run so that the MSI can take over so you get an incomplete report because Puppet is no longer running once the MSI shuts it down. So if you had anything else you wanted to do, you hope that the MSI upgrade completes successfully (because you don't get the report sent from the upgrade, and you don't get a success). Then you hope the newer Puppet installs fine and then checks back in once it is upgraded. So when I say it locks files instead of letting you replace them in place, it's because we have to force Puppet to exit so we can continue the upgrade. On Linux, while everything is in memory, you can completely change out the files on disk. When I say it is harder because of that locking, the longer explanation above is what I am talking about. Some folks would be fine with having Puppet just exit and not submit a report, but I'm not sure if everyone would be fine with that. I think we can do better, I don't think having Puppet exit to perform an upgrade is a sufficient answer. > > Bye... > > Dirk > -- > > *Dirk Heinrichs*, Senior Systems Engineer, Engineering Solutions > *Recommind GmbH*, Von-Liebig-Straße 1, 53359 Rheinbach > *Tel*: +49 2226 1596666 (Ansage) 1149 > *Email*: d...@recommind.com > *Skype*: dirk.heinrichs.recommind > www.recommind.com > > -- > You received this message because you are subscribed to the Google Groups > "Puppet Users" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to puppet-users+unsubscr...@googlegroups.com. > To view this discussion on the web visit > https://groups.google.com/d/msgid/puppet-users/5485B666.6030505%40recommind.com > <https://groups.google.com/d/msgid/puppet-users/5485B666.6030505%40recommind.com?utm_medium=email&utm_source=footer> > . > > For more options, visit https://groups.google.com/d/optout. > -- Rob Reynolds Developer, Puppet Labs *Join us at **PuppetConf 2015, October 5-9 in Portland, OR - * http://2015.puppetconf.com/ *Register early to save 40%!* -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
