The Flash has an internal mechanism to minimalize write cycles. So it is hard to calculate the total life time in a running Linux system. What I did to avoid too many write accesses is: Create a RAM disk of about 4M size and mount it on /var. Then copy a template of the var directory structure from any place you stored it on the flash to the empty /var because Linux needs some files to exist there. After that all system logging, printer spooling, process lock files etc. go to the RAM disk and disappear after switching off. Mount the any flash file system with the option noatime. This avoids to write the file acces time to disk when the file was only read accessed.
