[LEDE-DEV] Running init in a chroot LEDE Image
Hello everyone, Thanks a lot for an amazing project! I'm trying to run a rootfs chroot on my desktop computer to easen the development of userspace applications, but as I'm using ubus I need a complete LEDE environment. Using chroot also reduces the turnaround time for code/test cause I can just write code and it instantly is loaded on the image. I donwloaded the image from here: http://ci.libremesh.org/196/x86/generic/Generic/lime_default/lede-17.01 .2-lime-default-x86-generic-generic-rootfs.tar.gz Mounted all devices, did chroot... but I somehow need to call init to get ubus running (and all of the other supporting systems). Any suggestion on how to manually call init? just calling /sbin/init says the following: tmp# chroot lime /sbin/init WARNING: Variable 'led' does not exist or is not an array/object Press the [f] key and hit [enter] to enter failsafe mode Press the [1], [2], [3] or [4] key and hit [enter] to select the debug level WARNING: Variable 'led' does not exist or is not an array/object But nothing else.

I've used qemu before... this time I wanted to run it from a chroot because: * want to access a wireless device I'm not being able to access from qemu... a usb wireless adaptor ath9k_htc * i want to run an LEDE-based system (LibreMesh) on top of already running systems like Raspbian on a Raspberry-pi or ARMBian on a Banana- pi. I did the chroot and throught it I can access the ath9k_htc device... so the only pending thing is to run init somehow... or to startup the essential services manually.

Have tried. > Or making an image and run it insider docker? No... just thought first on chroot... but also LXC or Docker could work... any pointer? signature.asc Description: This is a digitally signed message part ___ Lede-dev mailing list Lede-dev@lists.infradead.org http://lists.infradead.org/mailman/listinfo/lede-dev

An additional comment, there seems to be a commit on trunk regarding this, https://github.com/lede-project/source/commit/be40d0a144937a788fa8902e3 335a25586acaa95 The commit is not merged on the last release. Will try that, but if you have experienced it, would be good to know!
