I like to keep up with the official kernel releases. As a result the
firmware they wind up requiring is newer than what is available in
firmware packages.

I placed the firmware from the git repo in /lib/firmware/updates/
which the kernel searches before /lib/firmware.  Kernel can
find them but update-initramfs cannot.

I have attached an initial patch that solves this. I am currently
using the resultng code and it is working fine for me.

The one thing the patch does not do is allow for a custom location
that can be provided to the kernel to search first.

This is because that's a little more complicated and requires a
decision wrt where to specify this location (ie the config file?).

 the subject line.]

These all seem to be harmless in practice, as the parameter values
should not contain metacharacters.

In _checkfs_once() *do not* quote $spinner or $force; if these
are empty then we do not want to add arguments for them.  Add a
comment to suppress the warning.

If we have a generic framebuffer device then there should be no
need to set up any backlight in early boot.

Also, backlight devices are sometimes handled by large drm drivers
like i915 which we don't want to include by default.

pthread_cancel() in libpthread.so.1 depends on functions in
libgcc_s.so.0, but uses dlopen() to link to it rather than having a
static dependency.  Handle this dynamic dependency in copy_exec so
that it doesn't have to be handled in every affected hook script.

"update-initramfs -c -k all" used to re-create initramfs images if
they had been deleted without using "update-initramfs -d", as it used
the state directory to determine which kernel versions should have
them.

Since commit f39625af "update-initramfs: Make "-k all" take over other
initramfs images", it ignores the state directory and is almost
equivalent to "update-initramfs -u -k all".

Change it to operate on all installed kernel versions.  This will
ignore which kernel versions suppressed initramfs generation, but
I think it's reasonable to assume users won't use these options
if they have installed such kernels.

This reverts commit 9c823ad2.  It did
not solve the problem it was intended to, because it used "$DESTDIR"
in the destination argument to copy_exec and would therefore copy to

Tighten permissions for /run/initramfs

See merge request kernel-team/initramfs-tools!22

/run/initramfs contains a log file from fsck of root file system,
which could perhaps contain sensitive information, for example if
/home or /var are also located there and fsck is triggered.

Let's tighten the permissions to 0700.

hook-functions: Add f2fs as base in auto_add_modules

See merge request kernel-team/initramfs-tools!24

For people wanting to change their filesystem to F2FS or for embedded
devices with eMMC or sdcard, add the f2fs module and its dependency as
base module. Moreover, this adds "crc32" as hidden dependency module for
f2fs.

This reverts commit da64d1a1, which
was a workaround for the inconsistent choices of interpreter path in
the early days of armhf and the limitations of copy_file at the time.
Now that copy_file automatically replicates symlinks and their
targets, we don't need to do anything special about the dynamic
linker.

An initramfs built for Debian 10 on armhf currently contains:

/lib/arm-linux-gnueabihf/ld-2.28.so           regular file
/lib/arm-linux-gnueabihf/ld-linux-armhf.so.3  link to ld-2.28.so
/lib/arm-linux-gnueabihf/ld-linux.so.3        link to /lib/ld-linux-armhf.so.3
/lib/ld-linux-armhf.so.3                      regular file

There are two *copies* of the dynamic linker as well as two symlinks
to one or the other of them.

After this commit, the initramfs contains:

/lib/arm-linux-gnueabihf/ld-2.28.so           regular file
/lib/arm-linux-gnueabihf/ld-linux-armhf.so.3  link to ld-2.28.so
/lib/ld-linux-armhf.so.3                      link to arm-linux-gnueabihf/ld-2.28.so

The /lib/…/ld-linux.so.3 symlink is no longer created, because Debian
armhf binaries all use /lib/ld-linux-armhf.so.3 as the interpreter
path, but it would be created if we ever switched over.

On Samsung Chromebook Plus (v1), messages and prompts printed during an
initramfs run aren't visible to the user unless the pwm_bl, rockchipdrm,
pwm-cros-ec and panel-simple modules are included. This commit includes
these when MODULES=dep and when MODULES=most.

For MODULES=dep: adds backlight and pwm to the dep_modules_add sys-walk.
Walking backlight includes pwm_bl and pwm includes pwm-cros-ec. Since
panel-simple isn't reachable from /sys/class/**, but it can be reached
from /sys/devices/platform/edp-panel, that path is sys-walked if it
exists.

When {efi,platform,simple,vesa}-framebuffer cannot provide a working
framebuffer device, graphics is sys-walked as well. Walking drm works
for rockchipdrm too, but also includes panfrost, so graphics was chosen
instead.

For MODULES=most: the modules are included in a new case 'fb' in the
auto_add_modules intended for modules providing framebuffer support
for machines where generic drivers don't provide one.
