Google’s Chrome browser
seemingly dominates the Internet at this point, but
that does not mean that everybody wants to run it. Chrome, of course, is
built on an open-source project called Chromium but is not
an open-source product itself; it includes a number of proprietary add-ons.
But the Chromium source is out there and can, with some effort, be used to
build a working, open-source browser; a number of distributors do so.
But Chromium is famously hard to package, and distributors have, at times,
struggled to keep up with it; a recent discussion in the Fedora community
has brought new attention to this problem.
