Hello,

I try to put links into the read-only rootfs which should point into a 
RAM filesystem.
For example I want to put the resolv.conf file into the tmpfs which is 
mounted at /tmp that the DHCP client can modify that file at runtime.

I tried to create a link in the projectroot:

cd projectroot/etc
ln -s ../tmp/resolv.conf resolv.conf


But then I get the following error with a "ptx go":

-------------------------------------
target: os-release.targetinstall.post
-------------------------------------

finished target os-release.targetinstall.post
make: *** No rule to make target 
`/home/user/development/bsp/branch2_tx53/projectroot/etc/resolv.conf', 
needed by 
`/home/user/development/bsp/branch2_tx53/platform-optimeas-tx53/state/rootfs.targetinstall'. 
  Stop.

If I create an empty file at projectroot/tmp/resolv.conf the file will 
be copied in the rootfs instead if the link...


What is the right way to create such links?
If I create an own package (in + rule) which creates these links, how 
can I ensure that my package is called as the last package to overwrite 
files from other packages ?


Best regards,

Matthias
