From b70993cf922411260b42986c5501b72550719f5b Mon Sep 17 00:00:00 2001 From: Robert Yang Date: Thu, 4 Jul 2019 12:12:37 +0800 Subject: bitbake: cache: Create a symlink for current cachefile So that people or other tools can easily know which one is being used, just like what we did for run.do_task and log.do_task, otherwise, we have no way to know it. I usually use "ls -t", but it isn't reliable since the one which is being used may not the latest one.
