init-install: Fixes the install script failing when not finding any mmcblk devices

2016-08-30T06:57:50+00:00

The init-install.sh and init-install-efi.sh scripts perform a check to see which devices are available on a booted system for installation. Recently, the way we check for these devices changed on 993bfb, greping for devices found on /sys/block/, this change caused the installer to fail (at least) when not finding any mmcblk devices, due to the fact that we call sh -e to execute this script, so any command (grep) or pipeline exiting with a non-zero status causes the whole script to exit This patch throws in a harmless true exit status at the end of the pipeline(s) of the grep commands to avoid the installer script from exiting, fixing the issue.

init-install*: /etc/mtab make a link rather than a copy

2016-08-17T09:35:41+00:00

Using a copy would only make management of devices erroneous and makes the system unstable in some scenarios as tools will have to manipulate both files separately. A link ensures that both files /proc/mounts and /etc/mtab will have the same information at all times and this is how it is handled on newer systems where there is such a need. Same is suggested by busybox. (From OE-Core rev: 9f9240d175acee274c04242fd5781094b3f5491b) Signed-off-by: Awais Belal Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

init-install*: only pick root mmc devices

2016-08-17T09:35:40+00:00

Some eMMC devices show special sub-devices such as mmcblk0boot0 etc. The installation script currently pick all of them up and displays it to the user which makes some confusions because these sub-devices are pretty small and complete installation including rootfs won't be possible in most cases. We simply now drop these sub-devices and only present the user with the root of such mmc devices.

initrdscripts/init-install*: Add rootwait when installing to USB devices

2016-08-17T09:35:39+00:00

It can take a bit for USB devices to be detected, so if a USB device is your rootfs and you don't set rootwait you will most likely get a kernel panic. Fix this by adding rootwait to the kernel command line on installation. Fixes [YOCTO #9462].

initramfs-live-boot: Make sure we kill udev before switching root when live booting

2016-08-17T09:35:38+00:00

When live booting, we need to make sure the running udev processes are killed to avoid unexepected behavior, we do this just before switching root, once we do, a new udev process will be spawned from init and will take care of whatever work was still missing [YOCTO #9520] (From OE-Core rev: e88d9e56952414e6214804f9b450c7106d04318d) Signed-off-by: Alejandro Hernandez Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

initrdscripts/init-install*: Select install target instead of looping through

2016-07-21T06:47:52+00:00

Its not immediately apparent that more than one install target could be available. With this change we list the available devices up front then prompt the user for which one to use, reducing confusion. Fixes [YOCTO #9919].

initramfs-framework: make rootfs module optional

2016-07-20T09:28:47+00:00

It still gets installed by default via RRECOMMENDS without having to update users of the framework (because without it, the framework is incomplete), but that recommendation can be overridden on a per-image basis.

initramfs-framework: Add support for PartUUIDs

2016-07-08T08:57:26+00:00

The rootfs can be addressed also by referring to the PartUUID value from the GPT. This patch enables such type of reference. (From OE-Core rev: 1ab2ca141d3defe4b80212e28ac7c3f2271e2515) Signed-off-by: Igor Stoppa Signed-off-by: Patrick Ohly Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

initramfs-framework: add retry loop for slow boot devices (like USB)

2016-07-08T08:57:26+00:00

On some hardware platforms (Gigabyte, qemu), detection of USB devices by the kernel is slow enough such that it happens only after the first attempt to mount the rootfs. We need to keep trying for a while (default: 5s seconds, controlled by roottimeout=) and sleep between each attempt (default: one second, rootdelay=). This change intentionally splits finding the rootfs (in the new "rootfs") and switching to it ("finish"). That is needed to keep udev running while waiting for the rootfs, because it shuts down before "finish" starts. It is also the direction that was discussed on the OE mailing list for future changes to initramfs-framework (like supporting a "live CD" module, which would replace or further augment mounting of the rootfs).

initramfs-framework: base: Ensures /run/lock is available

2016-06-23T13:26:16+00:00

Depending on the module we use, the /run/lock may be required. This creates it as part of initial setup and thus makes it available for every sub module.
