Comment # 9 on bug 1069441 from Ludwig Nussel

Moving over to Leap as this test is still red and getting rails to work sucks
big time still.

The work flow that works is

# zypper -n in -C "rubygem(rails)"
# zypper in gcc make ruby2.5-devel libxml2-devel glibc-devel libxslt-devel
sqlite3-devel
$ rails new mycoolapp --skip-bundle --skip-test
$ cd mycoolapp
$ bundle config build.nokogiri --use-system-libraries
$ bundle install --path vendor/bundle
$ rails server -b 0.0.0.0

That is far away from obvious and plug&play, at least not to me. So question to
the rails folks. Is that work flow expected and well known? If not, how about
documenting it in the wiki and/or release notes?

Moreover, can we make that easier? For example, there already is a devel_ruby
pattern. Would it make sense to just add the aforementioned devel package
requirements to this pattern, so instead of installing the rails gem we
document installing the pattern instead?

Also, can the nokogiri config be made default?
