See if you can change the flow here to skip the part about downloading to the working directory. Here's the issue:

For annoying yum reasons (which will hopefully be resolved in the next few months), it won't work when downloading to a NFS share. That means we can't tell people to mount all of /var/lib/pulp to NFS like we used to. Our instructions are to mount /var/lib/pulp/content, which is the final resting place for all content.

This approach of first downloading to the working directory means that the non-NFS mount will require quite a bit of space to store the temporary ISOs. That's not an ideal situation.
