with a few packages, files are not being properly created in /usr/share/locale/xx/LC_XXXX when I install the RPM. I mostly don't care about the files themselves, but I worry about what else is wrong.
Answer:
[root@dns-east rpm]# /bin/pwd /etc/rpm [root@dns-east rpm]# !grep grep -i lang * macros.imgcreate:%_install_langs en [root@dns-east rpm]#
Which is fine with me (although I am not sure it is the right default).
Now, off to file a bug report on yum-plugin-presto...
