initramfs-framework/udev: call settle before kill

2018-09-19T13:39:16+00:00

When mount command is executed in rootfs module of initrd, eudev creates
a loop0 device node, applies rules and adds a inotify watch to it. Right
after this step, we execute finish which first tries to kill any running
udevd daemon before doing a switch_root.

In some cases, it is possible that switch_root is executed before
inotify_add_watch was actually processed which would lead to errors like:

| inotify_add_watch(6, /dev/loop0, 10) failed: No such file or directory

Make sure that we process all the events in queue before actually trying
to kill udevd to prevent this race.

initramfs-framework: Allow directories with spaces

2017-09-12T15:53:31+00:00

When mdev module loads the Linux kernel modules, it can visit
directories with spaces. To allow that, we must quote the variable
otherwise it misunderstand it arguments as multiple entries.

Fixes:

| Freeing unused kernel memory: 3072K (80d00000 - 81000000)
| cat: can't open '/sys/devices/platform/Vivante': No such file or directory

initramfs-framework/setup-live: quote bootparam_root variable

2017-08-24T08:35:16+00:00

When bootparam_root was empty the if statement would resolve into
invalid syntax instead of short circuiting after the -z, causing a boot
failure.

initramfs-framework/setup-live: also boot live image if root=/dev/ram0

2017-08-19T08:19:12+00:00

Our grub and syslinux bootloaders both define root=/dev/ram0 for live
images by default. Kernel docs show that root=/dev/ram0 is just a
sentinel value for the kernel to mount the initrd as root, which then
mounts and switches to the real root. This is exactly what our scripts
do, so just check for root=/dev/ram0 as well.

See: https://www.kernel.org/doc/html/v4.11/admin-guide/initrd.html#operation

This fixes the issue where the new initramfs-framework scripts would not
boot live images that use grub or syslinux bootloaders.
