In general, variable history shows you full paths. For example: set in /home/<user>/poky/meta-yocto/conf/distro/poky.conf But when a variable is manipulated in bitbake.conf, the path only shows: conf/bitbake.conf Can we display the full path to bitbake.conf?
I've sent a solution to toaster mailing list.
