Joyent has a process to upgrade pkgsrc, one of those steps is:

PKG_PATH=http://pkgsrc.joyent.com/packages/SmartOS/2016Q4/x86_64/All
pkg_add -U pkg_install pkgin

This failed with an error that I mistakenly took to mean that my
kernel was not 64-bit. After looking at uname, and then isainfo, I
realized that the error was due to the Joyent pkgsrc I have installed
being 32-bit and the upgrade I attempted to install being 64-bit.

This has nothing to do with how uname behaves, which triggered me to post.

Thanks for verifying that. I hadn't realized that has always been the
behavior, OmniOS generally "just works" so I had not run into this
oddity previously, and my incorrect assumption in the subject.

I was aware of this, thanks to the thorough documentation on how this
works to provide both versions, hence my confusion about uname.

Thanks for the response.
