One thing I worry about is a kickstart being starved for entropy. Do you
want to hang for however long it takes, do you want to disable waiting
or provide a maximum timeout?

Depending on the hardware being used you will have more (or less)
entropy available. Last time I looked some of the network drivers
contributed, but not all of them.
