If you have a HDD available, why do you want to run on a production
server on a USB stick at all?

There are no potential problems when you install whole system to USB
stick or other flash card. You can then use your HD for data only.

There is one thing you should consider before doing what you asked for.
USB is slow! Slower then SAS or SATA. You would hardly see any
performance gains in boot up speed then. Additionally in "real" servers
a lot of time is spent on BIOS related procedures and with USB card you
must wait as well.

You should probably assemble a little cluster and then use kvm for
virtualization. It's very speed efficient to reboot virtual machines.
