Details
This file is located at /var/flash/ - but only exists in Freetz modified firmware.
freetz stores the persistent configuration of Freetz in a typically uncompressed tar file.
At runtime the contents are extracted to tmpfs at /tmp.
The config is processed by a bunch of mod* commands which are located in make/pkgs/mod/files/root/usr/bin.
These commands are installed to /usr/bin in the modified firmware and could be called from the shell.
modsave flash saves the freetz configuration from /tmp to /var/flash/freetz.
modload loads the freetz configuration from /var/flash/freetz to /tmp.
The TFFS device node is created in rc.tffs.sh. It uses mknod with the Major of the tffs device from /proc/devices
and a Minor of 60 (0x3C):
tffs_nodes_list="$((0x3C)),freetz" tffs_node_prefix="/var/flash/"
This only applies if the TFFS-Configuration uses AVM's TFFS filesystem, which uses character devices for each file.
Some models use YAFFS2 to store the config, which can create files on the fly.
Warning
AVM's factory reset performed by setfactorydefaults only clears the user configuration of the AVM Webinterface.
The freetz configuration is not cleared, even if you install an original firmware.
The TFFS still stores your config, and a later mod or a mknod will bring it back.
Keep this in mind when you sell a previously modded box! To be safe always use a Recovery.exe before selling it.
This is a problem for Cable models, since AVM does not provide a recovery for them.

A * in the Mod column marks info from Supportdata-Probes, which will always stay incomplete.
A ** in the Mod column marks info from Supportdata2 probes, which by their nature will stay way more incomplete.
A - in the Mod column marks manual research, the Firmware then shows where the item occurs, not the Relation.

The (main/scrpn/boot/arm/prx/atom) label in the Model column shows which CPU is meant for models with multiple Linux instances.
Note that this list comes from Supportdata-Probes, which can have arbitrary settings and come from different firmware versions.
It doesn't say much if a model is not listed here. It may be a missing supportdata file or just a disabled feature.
