The rootfs task runs under fakeroot. This converts the devshell to do the same, allowing the user easier debugging of problems like permissions for example.
I'm really after to provoke some discussion with this patch. There are a variety of cases where it would be desirable to run devshell in fakeroot context. This patch enables it for one, the image generation case but there are others. We have several options: a) Add these in on a case by case basis. Image generation is one which is clearly makes sense to me. b) Always enable fakeroot for devshell. The downside is some calls accessing the user's session won't work properly. You'd have to run those in the form "PSEUDO_UNLOAD=1 <command>" c) Add a new fakerootdevshell task which sits along side devshell but starts devshell with fakeroot privileges. Adding a new task is relatively expensive in parsing performance and in runqueue generation. I'm not sure whether there is enough of a case for two different tasks or that it would user friendly. I'm therefore seriously considering b) but would be interested in the opinions of others. The attached patch implements a) as a proof of concept. b) would be just adding those lines to devshell.bbclass instead. Regardless of which we pick, we need to document it, cc'ing Scott s he knows there is a change in this area brewing and needed before release.
