Fix failure in the osk-sdl "keyboard-font" check when there is a second
key starting with "keyboard-font" (as in osk-sdl MR 105):
==> initramfs: creating /boot/initramfs-postmarketos-allwinner-extra
ERROR: Font specified in /etc/osk.conf does not exist!
ERROR: postmarketos-mkinitfs-0.17-r0.trigger: script exited with error 1
cpio expects a newline-separated list of files from stdin by default,
and you can change that to a NULL-terminated list of files by using the
'-0' switch.
Previously we were passing a NULL-terminated list ('-print0') and using
cpio with the default setting. For some reason busybox cpio works with
that but GNU cpio doesn't like that and generates an initramfs without
any files (as it only gets "a single file").
With this change the initramfs generation works fine with both busybox
cpio and gnu cpio.
Fixes#815
Previously we added the header in the kernel packages but as we already
add the ramdisk header here and to simplify the process we also add the
addition of the kernel header into mkinitfs.
Read kernel module names from files in
/etc/postmarketos-mkinitfs/modules and print out which modules are
required by which of these files as the initramfs gets generated. Put
the default modules into a new 00-default.modules. This allows mkinitfs
hooks to add modules to the initramfs.
Parse the modules from a file similar to modules-load.d, with commented
lines and empty lines ignored. Add a simple test script for that and run
it in check().
Split mkinitfs.sh into two files, so the functions (now in
mkinitfs_functions.sh) can be sourced in a test. Such a test will be
added in the next commit.
Move $BINARIES_EXTRA into the get_binaries_extra() function, so its
$(find...) does not get executed when sourcing the functions file. Move
$BINARIES into get_binaries() too for consistency.
