* tiny-init: set proper S valuePetter Mabäcker2015-01-261-0/+2
| | | | | | | | | | | | Ensure that we are using a proper value for S, instead of the default value. All recipes must have a proper value set for S when solving [YOCTO #5627].

* tiny-init: Mount devtmpfs manuallyDarren Hart2013-02-222-2/+4
| | | | | | | | | | | When using an initramfs, the default for poky-tiny, the kernel can't automatically mount devtmpfs. Ensure it is mounted. This eliminates the need to create the ptmx device.

* tiny-init: Setup /dev/ptmx in initDarren Hart2012-08-012-1/+4
| | | | | | | | | | | | | | | | Fixes [YOCTO #2382] Without /dev/ptmx, ssh logins fail with: "PTY allocation request failed on channel 0" As the kernel support already exists in the linux-yocto-tiny kernel, create the /dev/ptmx device in tiny-init so it works as intended.

* tiny-init: Basic init mechanism for poky-tinyDarren Hart2012-06-263-0/+72
Currently poky-tiny images will boot and run /bin/sh, which results in error messages to the console about being unable to open the tty and job control being disabled. The shell must be session leader to open the tty, and the tty must not be /dev/console (it should be a vt or a physical tty like ttyS0), the tty is required for job control (handling signals, etc.). The goals of poky-tiny are to be an initial starting point from which to build a distribution that does what you want, and NOTHING more. This patch results in a system that boots with the virtual filesystems mounted, the local network interface up, and a shell with job control running, and a hook (/etc/rc.local) for easy customization. Nothing else. Enabling the basic busybox init, including the ability to give the controlling console to commands starting with a dash in inittab results in a 5664 byte delta (compared with 2560 bytes for enabling setsid and cttyhack). Note that the help in busybox suggests the cttyhack may be more reliable than the init support for handing over the controlling terminal. So the difference between using a standard init and just enabling the two options is about 3k, but enabling setsid and cttyhack may enable others to things besides what I am looking to do. Enabling init in both DISTRO_FEATURES and busybox is fairly trivial to do, so I think it's better to leave that as something to add if needed, rather than something to remove, as that is more consistent with the goals of poky-tiny. Thanks to Tim Bird for his suggestion to include support for rc.local by default.
