> Is there a way to have repoquery report on resolution failures? The current behavior is problematic because there is no way to tell when resolution failed; repoquery silently ignores capabilities that didn't resolve and only return what it could resolve, which means the result isn't trustworthy.
Yeh, it's not intended to do that it's just an output modifier. If
you want to test that a package is installable then you want to do
something more like:
yum --releasever=/ --installroot=/tmp/blah --assumeno \
...or the other way is to run repoclosure to make sure the entire
repo. works. In theory we could just print the requires if we can't
resolve it to anything, but I'm not sure that'd be useful to you or
