* Update buildroot-patches for 2020.11-rc1 buildroot * Update buildroot to 2020.11-rc1 Signed-off-by: Stefan Agner <stefan@agner.ch> * Don't rely on sfdisk --list-free output The --list-free (-F) argument does not allow machine readable mode. And it seems that the output format changes over time (different spacing, using size postfixes instead of raw blocks). Use sfdisk json output and calculate free partition space ourselfs. This works for 2.35 and 2.36 and is more robust since we rely on output which is meant for scripts to parse. * Migrate defconfigs for Buildroot 2020.11-rc1 In particular, rename BR2_TARGET_UBOOT_BOOT_SCRIPT(_SOURCE) to BR2_PACKAGE_HOST_UBOOT_TOOLS_BOOT_SCRIPT(_SOURCE). * Rebase/remove systemd patches for systemd 246 * Drop apparmor/libapparmor from buildroot-external * hassos-persists: use /run as directory for lockfiles The U-Boot tools use /var/lock by default which is not created any more by systemd by default (it is under tmpfiles legacy.conf, which we no longer install). * Disable systemd-update-done.service The service is not suited for pure read-only systems. In particular the service needs to be able to write a file in /etc and /var. Remove the service. Note: This is a static service and cannot be removed using systemd-preset. * Disable apparmor.service for now The service loads all default profiles. Some might actually cause problems. E.g. the profile for ping seems not to match our setup for /etc/resolv.conf: [85503.634653] audit: type=1400 audit(1605286002.684:236): apparmor="DENIED" operation="open" profile="ping" name="/run/resolv.conf" pid=27585 comm="ping" requested_mask="r" denied_mask="r" fsuid=0 ouid=0

# Macro that builds the needed Makefile target to create a root
|
|
# filesystem image.
|
|
#
|
|
# The following variable must be defined before calling this macro
|
|
#
|
|
# ROOTFS_$(FSTYPE)_CMD, the command that generates the root
|
|
# filesystem image. A single command is allowed. The filename of the
|
|
# filesystem image that it must generate is $$@.
|
|
#
|
|
# The following variables can optionaly be defined
|
|
#
|
|
# ROOTFS_$(FSTYPE)_DEPENDENCIES, the list of dependencies needed to
|
|
# build the root filesystem (usually host tools)
|
|
#
|
|
# ROOTFS_$(FSTYPE)_PRE_GEN_HOOKS, a list of hooks to call before
|
|
# generating the filesystem image
|
|
#
|
|
# ROOTFS_$(FSTYPE)_POST_GEN_HOOKS, a list of hooks to call after
|
|
# generating the filesystem image
|
|
#
|
|
# In terms of configuration option, this macro assumes that the
|
|
# BR2_TARGET_ROOTFS_$(FSTYPE) config option allows to enable/disable
|
|
# the generation of a filesystem image of a particular type. If
|
|
# the configuration options BR2_TARGET_ROOTFS_$(FSTYPE)_GZIP,
|
|
# BR2_TARGET_ROOTFS_$(FSTYPE)_BZIP2 or
|
|
# BR2_TARGET_ROOTFS_$(FSTYPE)_LZMA exist and are enabled, then the
|
|
# macro will automatically generate a compressed filesystem image.
