FAI used to mount a RAM disk over the APT cache area. This is
"/target/var/lib/dpkg" when installing Debian. The relevant line in
fai.log is
Ramdisk mounted onto /target/var/lib/dpkg

There is a similar trick in use for yum. A grep over my configuration
space (which is based on the default examples) reveals:

class/CENTOS.var:FAI_RAMDISKS="$target/var/lib/rpm $target/var/cache/yum"

You can set FAI_RAMDISKS to "NONE" to turn off the feature.

If you still run out of disk space, you may mount a larger partition
over /var/cache/yum, replace /target/var/cache/yum with a symlink to a
directory on a larger partition, or even use a NFS mount (yes, I have
done this for apt, it works). This goes into prepareapt.SOMECLASS hook
for apt, check the name for case of yum.

You may want to make a copy of the content of /target/var/cache/yum
before you replace it with a symlink or mount over it, and unpack the
original content at the new location.
