This is done automatically, but only if the 'flatfsd' daemon is built. 
You can see it in petalinux-dist/lib/Makefile, under the romfs: target.

It creates symlinks from /etc/* (group, passwd etc) to /etc/config/*

This permits these config files to reside on flash-backed (and 
flatfsd-managed) storage.

The dependence on flatfsd is not ideal, the build more or less requires 
it.  A fallback to create hard /etc/group and friends would be easy, you 
could add it in vendors/MyVendor/MyPlatform/Makefile, under the romfs:: 
target.  Here you can add any custom platform settings you like, so 
something like

romfs::
[TAB]$(ROMFSINST} -a "root:x:0" /etc/group

would add the text "root:x:0" to the /etc/group file in the romfs.

Testing for the absence of flatfsd, and doing this automagically in the 
common romfs build target vendors/PetaLogic/common/common.mak would not 
be difficult - patches welcome! :)

Regards,

John
