Firstly:

Testing this in detail shows the actual issue:

Adding these files:
- etc/config/testfile    (contains a comment line)
- etc/config/network  (Altered config file, intended to overwrite the 
existing one)
- etc/config/wireless  (Altered config file, intended to overwrite the 
existing one)


The 1st file is properly added
The 2nd file is properly altered
The 3rd file seems to be ignored/overwritten again somewhere in the 
process.  It's not possible to provide a custom "wireless" file

summarized:  Adding new files seems to work,  altering used files ... 
not always


Secondly:

Is the content of the "files" dir written on top of the rootdir before 
generating the image? (so that the custom files are part of "rootfs" 
partition)
Or are they added using the FILES option in the image generator (making 
them part of "rootfs_data" partition ?)

Some filesystems (like ubifs) seem to act strangely when doing the 
initial boot after flashing while a rootfs_data overlay partition 
containing changes is also provided at this time.
immediately running "sync" after the initial boot finishes seems to aid 
in ensuring the custom changes are not lost on the 2nd boot.

The new mtd-utils patch series seems to have lowered the likeliness of 
the issue occurring..   but I've seen it again on some files.


Thanks again,

Koen
