Hi all, I also support the opt-in idea. This would be useful for us. To keep the current behavior for UZH the default could be to opt-in=True for everything but still provide the option to disable some features by doing the opt-out
I have also modified my playbooks to disable selinux. Personally I have found selinux to give more headache than advantages and for a temporary cluster I find more convenient to disable it. I would also suggest that the default behavior in elasticluster could be to keep selinux disabled. regards, Pablo. 2017-08-15 17:04 GMT+02:00 Laura Poggio <[email protected]>: > Dear Riccardo, > I am just starting to use elasticluster, but I think the idea of opt-in is > a good idea, especially with larger libraries such as python or R. > > Thanks for all your efforts! > > Laura > > On Tue, 15 Aug 2017, 13:41 Riccardo Murri <[email protected]> > wrote: > >> HI Julien, >> >> thanks for replying!
