flatfsd is a means of mounting a writeable yet persistent storage region 
under the /etc directory.  Typically, uClinux targets mount the root 
filesys as read only on a ROMFS filesystem - fltafsd and supporting 
scripts mounts a ramdisk under /etc/config, that is backed up to flash 
partition /dev/flash/config.

The flatfsd daemon manages this backing process.  There's a good article 
about flatfsd on ucdot.org - just search and you'll find it.

The reason your system behaved the way it did is that by default, I have 
the vendors Makefile setting up /etc/passwd as a symlink to 
/etc/config/passwd - this allows you to change the password at runtime, 
and have that change be persistent.  Since you disabled flatfsd, the 
link was broken and so it goes...

Hope this sheds some light,

John
