There are actually a couple of ways around the SD wear issue, even though people seem to dearly LOVE SSDs with the exact same issue;

1.) Use a USB drive.

2.) Somewhat more esoteric, PXE boot and run from an NFS image.

The how-tos for the later seem to avoid talking about how to set up a proper PXE boot environment using ISC DHCP, but I'll crack that nut shortly.

I love PXE and use it to install windows 7, freebsd, VMWare and a whole bunch of Linux distros in my home lab
