initramfs-live-boot: create /dev/console

2015-09-06T14:26:24+00:00

Some kernels, for example linux-yocto 3.19 for qemux86, fail to execute /init in an initramfs unless there is already a /dev/console char device in the initramfs. Booting then fails with: Kernel panic - not syncing: /dev/console is missing or not a character device! Please ensure your rootfs is properly configured The panic itself comes from a linux-yocto specific patch to kernel_init_freeable in init/main.c, but even without it, that function will print an error when /dev/console is missing. The kernel's Documentation/initrd.txt also mentions creating that device. It remained unclear why this is not a problem on other machines. On intel-corei7-64 from meta-intel, something (the kernel?) creates /dev/console and /dev/[012] before transfering control to the init script. In that case, creating /dev/console in advance is not necessary, but does not cause any problem either.

meta: set proper S value

2015-01-23T11:36:27+00:00

After removal of auto-creating S we must ensure that all recipes are using a proper value for S. Fix all recipes that only need to set S equals to WORKDIR. [YOCTO #5627] (From OE-Core rev: 9d220b1bfe4589736604dd5a7129e3699377d830) Signed-off-by: Petter Mabäcker Signed-off-by: Richard Purdie

Move boot media to /media/realroot for easy access after boot.

2014-07-10T16:38:33+00:00

There are cases where software after boot may need to know the current boot disk. Under the current system, it is not guaranteed which disk is the boot. While /media/sda is a good guess, it isn't always right, nor is it a good assumption that only one boot disk is in the system. This gives a standard path to the original boot disk mount which can be used to, for instance, update the syslinux file on the boot media with a newer kernel, or updating the boot parameters to add user options for future boots. Knowing which disk is the boot media keeps from updating the non-boot disk when for instance multiple syslinux boot medias are plugged in (ie ensure correct syslinux is updated when the booted system is updated).

Replace one-line DESCRIPTION with SUMMARY

2014-01-02T12:50:18+00:00

A lot of our recipes had short one-line DESCRIPTION values and no SUMMARY value set. In this case it's much better to just set SUMMARY since DESCRIPTION is defaulted from SUMMARY anyway and then the SUMMARY is at least useful. I also took the opportunity to fix up a lot of the new SUMMARY values, making them concisely explain the function of the recipe / package where possible.

initrdscripts: unionfs cleanup

2013-06-28T10:02:40+00:00

The unionfs has been disabled for more than a year and it's not going to be used any more. This patch cleans up the unionfs related code. [YOCTO #4761] [YOCTO #1487] (From OE-Core rev: ba5e437bc7335468a70ea293496f78e1a9d66287) Signed-off-by: Chen Qi Signed-off-by: Richard Purdie

initramfs-live-boot: explicitly depend on udev-extraconf

2013-04-15T14:58:15+00:00

init-live.sh depends on udev performing automounting, which happens in udev-extraconf. Explicitly depend on it so that we always have it installed. (From OE-Core rev: a608d74e69ca1efe5f2b176c000fb8212797d056) Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

initramfs-live-boot: Set RDEPENDS on the specific package that needs it

2013-02-04T16:42:47+00:00

Set the RDEPENDS on the specific package that has the dependency and stop it being applied to for example ${PN}-doc (and others). (From OE-Core rev: 7437a864f03ff56a4fba9d8ce9baf845b945ed9e) Signed-off-by: Richard Purdie

initrdscripts: fix udevd in the live boot init scripts

2012-11-12T22:31:20+00:00

udevd moved location and isn't in $PATH anymore, so use an absolute path to start it. The control socket path moved too, so mkdir the directory it's in. Mounts the new devtmpfs on /dev device tree.

initramfs-live-boot: Disable unionfs until its issue with the system rootdir are resolved

2012-04-22T15:00:26+00:00

There are issues with the current unionfs when making a union mount over "/". Until these are resolved we can't use unionfs for live booting so disable this temporarily as a workaround. unionfs is usable in other circumstances.

initrdscripts: fix init-live.sh and use unionfs

2012-04-11T11:15:32+00:00

[YOCTO #1487] When booting up with liveCD image, init scripts can't work well on read-only filesystem. Unionfs, which is supported in Yocto kernel, allows a filesystem to appear as writeable, but without actually allowing writes to change the filesystem. Use unionfs to mount rootfs and make root file system can be writen when using liveCD to boot up. Set UNION_FS variable depending on kernel config, so that it can work with kernel which doesn't have unionfs feature.
