koen, fathi, riku,
i am having issues with auto-serial-console that was initially done by marcin.
https://git.linaro.org/gitweb?p=openembedded/meta-linaro.git%3Ba=tree%3Bf=me...
the main issue is that it conflicts with BSP layer that uses SERIAL_CONSOLE variable. It is very much expected for a BSP layer to set SERIAL_CONSOLE variable. In which case OE will automatically start a serial console
http://cgit.openembedded.org/openembedded-core/tree/meta/recipes-core/sysvin...
So when using auto-serial-console with a 'proper' BSP layer that set SERIAL_CONSOLE(S) we end up with starting the console twice, one added by OE, one by auto-serial-console. So far, all our OE builds are not using a proper BSP layer, so that's why you don't see the problem, but for our builds we use proper BSP layer...
right now, auto-serial-console does 3 things:
1- figure out the serial console port from /proc/cmdline 2- start a console on #1 3- automatically login as root
I believe that we should 'do something' to split them into several packages so that we get more granularity. At least #3 needs to be separated out, as #3 is a 'policy'.
The recipe itself is already a policy thing, so we should look into a way to have different images for proper builds (using BSPs) and hwpack based deployments. This will also make non-linaro users of our layers happy.
I would almost expect that 'being able to automatically login as root on the console' is a feature that could (should?) be added to oe-core somehow. What do you think koen?
I agree
I looked into that, but there isn't any obvious (and trivial) way to do that, but it's certainly doable inside an IMAGE_FEATURE for example.
Right. But keep in mind that sysv is not the only init system supported in oe-core. FWIW, systemd already autospawns a getty on every entry listed in the console= kernel cmdline.

this email is just to start the discussion and get some advices, e.g. i am not asking you to do it ;-) i can work on it, but want to make sure i do it right, with an 'upstream' path if possible.
thx
