I found one reason - if local repository files are updated, and hashes needs to

Running 'yum clean expire-cache' seems like a more efficient way to
accomplish this. I'd hope that in a typical "install os, install vdsm"
scenario we wouldn't need a more heavy-handed cleanup.

Subject: [vdsm] Why do we need clean yum cache during bootstrap?
Hi Douglas,
Why do we need clean yum cache before installing packages during host
installation? It could cause a ssh timeout somtimes. On my test VM,
it
needs several minutes do download yum metatada. Please see the test
below:
