I know it's not the most common case, but there's no denying RVM is becoming increasingly popular in the Ruby community. -- Gaveen Prabhasara ___ ruby-sig mailing list ruby-sig@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/ruby-sig

Yes, but that completely ignores upstream. That is, most of the software in Fedora comes from upstream, and is (or may be) packaged for many different distributions, some of which may have put ruby in another location. To be honest, typing #!/usr/bin/ruby is hardwired into my brain, but I do think that the #!/usr/bin/env ruby is more generic (and portable). -- Chris Lalancette ___ ruby-sig mailing list ruby-sig@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/ruby-sig

And of course the reasons stated in [1] makes much sense (and it is aligned with my 'reliable tool chain' note).

I would prefer the first one, because in Fedora, Ruby interpreter is always in *known* place (/usr/bin/ruby). There was also some tries[1] to actually prohibit use of #!/usr/bin/env completely in Fedora packaging. Also FSH guarantee some interprets in /usr/bin, but AFAIK Ruby is not there[2] yet.
