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.targetinst= all.post
-------------------------------------

finished target os-release.targetinstall.post
make: *** No rule = to make target `/home/user/development/bsp/branch2_tx53/projectroot/etc/res= olv.conf', needed by `/home/user/development/bsp/branch2_tx53/platform-opti= meas-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
