I know this has already been answered, but what I do on the Ts7250 (or anything
with the TS 2.4 kernel) is add this to /etc/fstab:
ramfs /tmp ramfs 0 0
This gives me /tmp as a volatile filesystem that I do all the application
logging to, and temporary files. The files there are lost during a power cycle
but at least it's not wearing out Flash. And it's a lot faster than Flash.
