One of the tricks I use for diskless systems is to mount a ramdrive in a
union mount with a read only nfs mount.  This allows filewrites (to the
ram drive) but old originals are retrieved from the ramdrive.

This is done on FreeBSD, but is effective enough for getting a fully
functioning system (yes, Postgresql included).  Takes quite a bit of ram
though.


Perhaps there is a toolkit for windows that can do similar union mounts?
