Colin Walters 118178cef1 tree-wide: Fix C++ range iteration to use references 
This is actually a perfect example of the tradeoffs involved
in our team of C/Rust programmers trying to use C++ so we
can use cxx-rs =)

It turns out that "for (auto foo : bar)" is really yet another
one of those C++ sharp edges just waiting to cut.  That
version does a copy of each value; one almost always wants to use
"for (auto & foo : bar)" which like Rust's `.iter()`.

In most of our code we were OK making copies, they were just
a performance hit, but in another place I was relying on the
"side effect" of `.c_str()` but that meant our value got
destroyed.

rpm-ostree: A true hybrid image/package system

rpm-ostree is a hybrid image/package system. It combines libostree as a base image format, and accepts RPM on both the client and server side, sharing code with the dnf project; specifically libdnf. and thus bringing many of the benefits of both together.

Features:

  • Transactional, background image-based (versioned/checksummed) upgrades
  • OS rollback without affecting user data (/usr but not /etc, /var) via libostree
  • Client-side package layering (and overrides)
  • Easily make your own: rpm-ostree compose tree and CoreOS Assembler
