From: Stefan Agner <>

When creating a custom image which uses the DATE variable the basehash
seems to change every day and lead to errors such as:
ERROR: console-tdx-image-2.7.6-r0 do_image_customimg: Error executing a python 
function in exec_python_func() autogenerated:

The stack trace of python calls that resulted in this exception/failure was:
File: 'exec_python_func() autogenerated', lineno: 2, function: <module>
 *** 0002:set_image_size(d)

Add DATE to the variables which should not get expanded early and to the
vardepsexclude list for the image task.

I am not that deep in OE usually and I am not sure if I miss something
completely here... It seems to solve the issue for us though. Does that
change sounds reasonable? Could it be done in the custom image class file?
