(adding TripleO because of potential effect)

Hi all,

I'm working on making ironic-python-agent images smaller than they currently are. The proposed patches already reduce the default image (as built by IPA-builder) size from around 420 MiB to around 380 MiB.

My next idea is to get rid of RPM and YUM databases (in case of a CentOS/RHEL image). They amount for nearly 100 MiB of the uncompressed image:

$ du -sh var/lib/rpm
91M var/lib/rpm
$ du -sh var/lib/yum
6.6M var/lib/yum

How important for anyone is the ability to install/inspect packages inside a ramdisk?
