The asterisk-gui writes into its source directory (/var/lib/asterisk/static-http/config) a fair amount to grab the output from system commands that it executes. There is no reason why this has to get mirrored onto the flash by unionfs. I could probably figure out how to modify the asterisk-gui to write to some temp directory (that would be ramdisk only, and not unionfs). Does astlinux have such a place? Also, syslog files are another source of constant flash writes (asterisk, dhcpd, others are always writing). Can this be moved to a ramdisk that is not unionfs?
What else (other than voicemail and CDR) is updated to flash on a regular basis?
