The flatfsd daemon, enabled by default, uses /dev/flash/config as
backing store for the RAM based filesystem mounted at /etc/config

This is a simple, robust way of having persistent, writeable files in
/etc (often just symlink /etc/XXXX to /etc/config/XXXX).

You can get rid of the config partition, but you'll have  to disable
flatfsd in your user build.  There may be some other dependnecies as
well, for example in the u-boot config scripts where we generate MTD
partition info.

Regards,

John
