[Users] [PATCH 5/6] fedora/config/install-post: do not abort if YUM_REPO is unset

[Kir Kolyshkin]

It looks like a proper check if $YUM_REPO is set is present, but in fact
due to 'set -o nounset' we will get the following fatal error:

  YUM_REPO: unbound variable

Fix that by using bash feature of substiting some value if variable is unset.
Apparently in this case it doesn't complain about unbound variable.
